I personally enjoy riding my scooter in nursing homes it really gets the juices flowing, all those old ladies just staring and the best part is that none of them can catch you cuz they all have their walkers and the floors are so smooth you can just ride for days
but if your really looking for something fun to do i would recommend adopting small children and selling them on the black market the look on their faces in priceless when they get taken away
also try to find a wheel chair basketball game or some kind of group who are disabled and ask to join in and if they say no make fun of them until they chase you and run away because you have legs and they dont and if they do let you join them put the ball above your head and laugh at them because they cant reach it (this also works with midgets and small children)
just some of my personal favorites try each of them at least once and youll get hooked
