My co-worker Damon started a garden this year. He has two raised beds. He built these removable fences to keep the dogs and squirrels out of his plants. Made them out of PVC, glued all the fittings together, added hose connection, and drilled holes on the top pipes to create a sprinkler. Pretty neat idea!
