This is a note to Melissa Furash re: pvc pipe. I just bought a 10 foot length of pvc drainage pipe at Home Depot for $3.97. The pipe is a cheap grade and has little ventilation holes in it. It is not clear, but the fuzzies race through it so fast it doesn't matter. This type of pipe comes with t-shaped connectors for about $150, so we hack-sawed the 10 foot pipe into lots of sections and built quite an a-maze-ing maze. Katherine [Posted in FML issue 1565]
