I was at the local Home Depot the other day, and wandered past the clearance rack. They had some heavy steel christmas tree stands marked down to $1.00. I bought the last five they had. I plan to make some PVC "trees", mount them in these stands, and drop them in. You never know where you might find cheap structure material. You just have to keep your eyes open all the time.
I always say one man's trash is another man's treasure! I find most of my blocks and wire that way where they were just discarded.
