At my place of work we have two tennis courts which have been here for years. We finally got the approval for court resurfacing approved and they started this week. It has been a fascinating process to watch. They first took down the nets. Then they did what looked like a belt sanding on them. Then pressure washing. Yesterday they put on two coats of some black liquid stuff. Not sure what is next... I was talking to someone about the cost yesterday. I thought it was around $7k. Turns out it was more like $18k. High cost of petroleum is part of that. Anyway, it looks like nothing I would want to take part in, especially in the 100 degree Carolina sun. We'll see what happens today.
