So, Paul and I consulted the SQFT garden book and learned how to make some critter-control structures. These are simply 1/2" PVC piping (found in the plumbing section of your local home improvement store) cut to size, curved into an arc, and stuck into the edges of the SQFT box. A cross piece is then added to the top with cable ties, and netting is then draped over the entire thing. We have to find a better way to hold down the netting for next year. The blocks we have here are too large and we trip over them.

A special little "critter" I found in my garden!
