I found a cool design for a composter made from a 55 gallon drum, some metal pipe, some hardware, and some 2x4's. I am interested in building one, but I am not sure where to find food grade 55 gallon drums.
Here's the site for anyone that was interested:

Any thoughts on where to find a food grade 55 gallon drum?
