Thanks Bruce.
I just got back from an unsuccessful lunch. I went to Hobby Lobby and couldn't find any cheap flower pots, they were all $40 and I'm not paying that much to just break it when I get home. Plus they're all painted and have a sticker that says "not food safe". So I went to walmart where the garden center is apparently shut down for the season, go figure. So they didn't have anything. My next stop will be the home improvement store to get some sewer pipe. We're expecting 10" of snow tonight, so if it's coming down hard after work I'll go straight home rather than risk my life on the road.
