We have about 25 275-gallon totes and about 15-20 55-gallon drums that previously held food grade emulsified vegetable oil that are available free to good home. They still have a bit of residue in them, but it isn't terribly hard to rinse out. The catch is that you will need to pick them up at former Kelly AFB in San Antonio between now and this Thursday. If you are still interested, let me know either via PM or using my user name at swbell dot net and I will give you contact info for the site manager.
