Then I found out I was a dork! When I was putting the mesh cover on, I decided that I would put the clean side up. One side was noticeably dirtier than the other side, so I thought that the cleanest side would have been the top since it took all the rain over last winter.
I realized about 3/4 of the way through that I was putting the cover on upside down, so I went ahead and finished putting it on. Now I have 2 big black rubber squares on top at the corners of the steps. I guess these are protection for the cover for when the middle goes down from snow so it doesn't rub against the corners and tear.
So the only real question is, should I leave it or flip it?
