rain barrels $5 each
 

At the Coke bottling plant on Burnet, just north of 183. These are 55
gallon plastic drums, originally containing the Coke syrup. FDA sez
they can only be used once so they have a giant pile of them sitting
outside. Each has 2 3/4" pipe thread fittings on it. I'm getting a
bunch to use as a collection system for gardening, when it's done I'll
try to post some pictures. Call the number in the phone book, and ask
for "Emory". They also have a smaller barrel, maybe 45 gallons.
