Racquetball court.......aaahhh yes, I remember now.........
I did one a little over a year ago, needed a 4 wheel drive vehicle to get in, large log cabin, 5-10 acres, in the middle of the mountains. I couldn't believe it when he showed me the full regulation size raquetball court. The best I could do was to find a couple of properties within 40-50 miles with large shop buildings.
