I want to make my little run taller so I can walk in it, and put a roof on it. I had a tarp on it, but our first big wind storm tried to make it a parachute and I almost lost the entire small run. I want to attach the roof to the big run (6 ft high), and have it go down to 5 1/2 feet (if that is enough of a drop). How do I do that without it becoming a parachute again? I'm not very handy yet...I just got a miter saw so I can cut wood easier, but that's the only power tool I have....lol!
