Home Projects: An "On The Fly" Fence

My wife has an impressive vegetable garden growing on the side of our house. She has many different things growing, and we have picked a few vegetables out and included them in some very good dinners so far.
We have noticed in the past couple of days that something is getting into it though. Not eating anything, just stepping in it. We had some sorrano peppers getl completely ruined and another strawberry (not that strawberries are a vegetable) branch broken off. So, we decided to make a quick fence to keep whatever this is from getting in. We think it's a dog down the road. Either way, let's hope this deters it.
