Rock Lake 2017 Update

Posted in General

Hello all,

We are only two weeks away!  Th long range weather forecast is looking good and fire hazard is still low, which means that things are looking very good for the launch.  Please check out the following:

  • Things have seemed really quiet lately so I would love to hear back from people on whether they are coming.
  • We need people to step up for duty shifts!  If you go to, you will see a blank slate of shifts as NO ONE has yet to step up.  Please do so ASAP.
  • Anyone have some fireworks they are itching to set off?  As July 1 falls on this weekend, it would be great to add a little extra bang to the festivities. J

Lastly, a quick poll question.  We send out information via our website, Facebook page, and the various Yahoo groups.  Which method do you prefer to get your updates?

I will be sending out another update in a week with any last-minute details.  Let me know if there are any questions.

Rock Lake Update

Hello all,

 One week from today we will be launching!  Everything is looking good for a fabulous event.

 Launch Authorization – Check

Fire Permit – Check (or at least it is confirmed that it is on the way)

Porta potties – Check

Weather – Looking good with highs in the low 30’s, some showers possible Friday, may be getting a bit breezy Sunday. 

 With the heat, remember to bring lots of liquids and shade!  I have no idea what the mosquito situation is like, but you can be sure our little friends will be there.  Bring some repellant.

 We will be having our usual Saturday bonfire, so if you have some extra wood to contribute to the pile, bring it along.

 As mentioned, Friday night we hope to have some fireworks as it is Canada Day.  If you have access to some, please bring it along.

 Hoping to see a bunch of you out there.  I will be on site Wednesday already, so come out whenever you want.

Rock Lake 18 Update #1

Posted in General

Hello all,

Two months from today we will have started Day two of Rock Lake!  Wow, time flies fast.  (Especially as you get older. J)  Here are a couple of updates for everyone.

Motor Order – In talking with Angelo at Sunward, he has indicated that availability of some motors is a little spotty.  His advice is to order any motors that you need ASAP in order to have the best chance of having them for Rock Lake.  I assume that this would be the case for whomever that you use as a supplier.  We have set up a shipment plan as we did last year that will have your motors delivered to the site for the launch.  All orders must be in to Sunward ( before June 17, 2016 (and even sooner as per a comment above).  Please indicate at time of order that you want it shipped to Rock Lake.

Fire works? – As we will be launching on July 1, it seems in appropriate to have some fireworks no?  Barring a large corporate sponsor stepping up to sponsor anything, I think we will have to settle with the potluck approach.  Anyone that wants too, please bring anything you have!

Volunteers – As always, we need people to step up and help to pull this off.  LCO’s, RI’s, set up, tear down, etc.  Please head to to sign up for some duty shifts.

As always, let me know if there are any questions.

Rock Lake 17 will be held on June 26, 27 and 28th, 2015.  Please reserve the dates in your calendars!  More announcements coming soon.  As always, if there are any questions, contact Tim at This email address is being protected from spambots. You need JavaScript enabled to view it. .  To register for the launch, send registration form to This email address is being protected from spambots. You need JavaScript enabled to view it. .

There will be a different process for motors this year.  Your choices are:

Choice 1 – order from your vender of choice and have those delivered to your home prior to the launch to bring with you to the site. 

Choice 2 – I have contacted Angelo at Sunward and set up a process for a group order.  Here are the details:

Deadline for 75mm hardware and above and M impulse and above – May 15th

Deadline for all other hardware and motors – May 29th 

Place your order with Angelo at Sunward This email address is being protected from spambots. You need JavaScript enabled to view it. and he will get back to you on pricing, availability and payment options.  Make sure to mention that this is part of the Rock Lake order.  The order will be delivered to the site (via me, Tim Rempel) and you can pick it up there. 

There will be a small amount of non-warranty motors and some hardware on site from the LRA secret stash, but selection is limited.  If you want a specific motor, PRE ORDER!!

Update from the site

Things are looking very good. Gravel road is in good condition, not too much standing water in the pit, and weather is BEAUTIFUL!!

As usual mosquitoes are in full force and for some reason horse flies. Lots of Off is in order. Also lots of water and other liquids will be needed. :)

See you here!
