Crappy equipment doesn't matter! I remember when I first started I used two boxes and a broomstick. Now I have some poles with holes so I can put some poles through them. It works. I also have a dog walk. I took a saw horse for the top and had two boards hinged to the sides. Then I put cubeular boards underneath the hinged boards for more support. And just a hoola-hoop works fine for a tire.

I will try to find a pic of the dog walk.
