I usually throw a hard backhand with enough force and height to go over the fence facing you, and then to fade back to the left and still clear the other side of the fence. If you get it just right you can park it pretty close to the basket. High risk high reward through because more than a couple times I had enough juice to go over the first part of the fence but on the fade to the left it hit the fence and stayed out of bounds. People with strong sidearms can go the other way but there is a parking lot to the left as well that you have to be careful with.
