Thank you for clarifiing the type of shelter you are using- you've made what we call a "pole barn" around here, a roof and four open sides. This is a horse of a completely different color.

What you had described initially sounded more like a classic "half an A-frame" leanto a 30 to 60 degree slope, which as I said in another post has it's merits but many more limitations. I've been using that image while trying to wrap my brain around the use of one that is 20' on a side. It would make a great windbreak and heat/light reflector for a group, particularly opposite the living shelter on the other side of the fire, and maybe a reflector to get the attention of anyone using radar (mylar blankets do have a few uses), but I couldn't see what a 20'x20' leanto could be used for other than than that.

If you had mentioned that you were using other materials, I didn't see it. If I had to hazard a guess, the pine with it's pitch is serving as part of the structure of your roofs material, actually glueing other stuff to it?

And there is an easy way to get a timestamp- take the picture with your watch in the way. <img src="/images/graemlins/smile.gif" alt="" /> Depending on what format you use, it may be possible to mine the time the datafile was created by examining the file itself as a text file, but that varies by format.

As for the "few minutes", I've reexamined this thread. I may have imported something from another thread, and for that I admit and apologize for my error. An hour may be marginal, but not utterly inconvievable, particularly if you have a large brush pile on hand for roofing matieral. *sketching a short bow* Without meaning offense, I think we both need either more or less caffine.

(BTW, you had mentioned quiting smoking- my method was to switch to a pipe. It takes time to fuss with it, and if you smoke it outside in winter, after a while, you find yourself needing to be warm more. You don't really have much winter, but I suppose sticking the pipe, tobbacco and lighter in the freezer might simulate enough of the effect, particularly if your teeth are cold sensative.)

So we've returned to my origional point of contention- how are you waterproofing this roof? Particularly with this shallower angle. How thick is the total material on your roof, and how often do you have to repair it?
