What you see here is the parking lot of my local YMCA. Please focus your attention to the upper parking lot. The lot is set up fairly well in my opinion for the space they have to work with. Every other row has a no parking zone so that you could zigzag through the lot when looking for a space and would not need to reverse back of the row is full. I have highlighted this with the red line.

When I arrive, the parking lot is maybe 50% full however people will park in those NO PARKING areas. I don't quite understand this. I am assuming that most of the people are here for some sort of exercise. Is that extra walk going to over do it for you?
