I have gotten several plastic drums (30 gal, maybe?) from a local outfit that gets floor cleaner in them. I cut a hole in one end and use them for carrying water to trees for several weeks to be sure they're really well-rinsed. Add that 2x4 for stability and you're set.

Free for me...

In a lifetime, the average driver will honk 15,250 times. My wife figures I'm due to die any day now...
