Most indoor playgrounds are for children under 12, it would nice if there was one for older people, Once, I was playing at an indoor playground when I was little and I went on this pulley thing, and there was a raised area where you could stand and grab the pulley, and I was able to do that, but the thing stopped when I was on my way down and I got stuck in the middle, my feet wouldn't reach the ground! So being too slow can be a problem too!
I still sometimes go to public parks, I can still fit in most of the equipment.
I once saw teenagers on a ride at the mall for little kids! I hope they could get out!
