Lots of slider threads lately and I found this on craigslist so I thought I'd post it. 55 gal. drums for $5 each and he says he can help move them.
http://lakeland.craigslist.org/for/607969595.html I want to buy them and build one but I live in an apartment and I don't even know if the local lakes would allow it. If someone around here is going to build one, let me know...
