Snow Removal

I have a job helping my friend push snow at his storage lots. He clears the north lot and I do the south one. It takes a couple of hours and helps him out. He has 2 pickups with snow blades on them. I really enjoy doing it but we just got 5-7 inches of snow and I'm healing slowly from knee surgery so couldn't help him. We are supposed to get more snow in the next 2 days so I'm going to try to do it.
