I found some Rubbermaid commercial bus tubs today that were to good to pass up. They are as thick if not thicker than a cement tub. They measure about
20 x 15 x 5. If anybody in SE Virginia is interested let me know because there are several hundred more. If anyone else has already tried this please let me know how it worked out. They are real similar to these.
