I remember there was a link posted last winter to very unique homemade portable shack that somebody had made. I think this person was in Southeast Michigan but I can't be sure. The shack itself was an accordian type shack with wood on either end with some sort of dark fabric (I think) or poly tarp (maybe). It seemed like a good deal of craftsmanship went into it's construction. In fact, I think the guy was received all kinds of offers from folks at this site if he went commercial with his design. It this makes any sort of sense to somebody, could you post a link to the construction page that gentleman posted for his shack. Sorry I can't be more specific...I should have bookmarked it at the time.
I'll post this in the shanty section as well.
Thanks in advance.
