We're getting ready to bring home two new baby goats within the next couple of weeks and we've been finding a use for all the free stuff we been finding on craigslist that's been piling up in the yard -- I knew it would all come in handy. The pile is getting smaller now.  We're not master craftsman by any means but we've been winging it pretty good I think with only two days work into it for now.  The walls are some tough shipping crates that we braced  with some 4x4 posts and we also used a telephone pole dug deep at all four corners.  The trusses we were lucky to find someone giving them away for free out of an old mobile home.  The OSB roof was the only thing that cost us the most out of the project.  Even all the wood fencing that will eventually enclose a garden area was scrapped and left out on the corner for free.  It sure is nice to be able to come across such good finds. I don't know how we all did it before the internet.  Still have some work to get it all finished but I thought we would share the project in progress.
