I have started a discussion on the SD Burners site to coordinate part of the rebuilding effort at Madre Grande, namely, the construction of bjurts (a yurt-like structure, see bjurt.com). Here is a link to that thread:

and here is a copy of the first post of the thread:

Greetings fellow burners,

I talked to Tracey at MG yesterday, and she is very interested in getting a few bjurts (bjurt.com). She is bringing it up at the meeting today, so I should know more in a few hours.

But for now, let's start with the logistics:

We don't yet know when we can get back into MG, but the most likely work weekends would be either 11/17 (the weekend before Thanksgiving) or 12/1 (the weekend after). If possible, we want to get these made before the rains start (if it's going to rain this year).

The goal is to build 5-10 bjurts, place up 5 on-site and the rest to other locals in need.

The main on-site resource will be ash, so we would have to bring everything else. There may not even be porta-potties, so we may be using camp toilets (I can bring a mini-bjurt to give privacy).

While this list is preliminary, here are a few things I think we need:
Event coordinator - Carl and I are working closely on the overall bjurt effort, but it would be handy to have someone run the camp (placement, food, water, public relations (talking to the cops)).

Generators

Extension cords

Drills and 1/4" hardened steel drill bits (I have one drill press and one bit, but we should have more to drill in parallel)

Pliers, hammers, wrenches (crescent and socket), files, and other assorted hand tools (I will bring some, but we need more)

Camping toilets (if porta-potties are not in place)

Shade, eating, and sleeping structures (I can bring shade structures (I have lighter structures than the bjurts as long as the winds are low) and we can sleep in the bjurts Saturday night)

Tables, chairs, cook stuff (I can bring a portable BBQ)

Tarps (we have enough billboard vinyl for almost 10 bjurts, but for the roof, silver tarps would block the sun better and may be easier to fit)

3/4" EMT conduit (I (Athena in LA, actually) am working on getting this donated, but it may not come in time)

Pins and clips (I have enough of these for the initial build, but I am going to try to get Fastenal to donate some)

Happy, hardworking people (10-20, the more we have, the faster it will go)

That's all I can think of for now. Please reply to suggest other things we might need or to let us all know what you can volunteer.

We will make this happen,
-bender
