outdoor gaming?

[Muffincat]

Martial arts is always a good bet; I know it was briefly mentioned before, but you might want to see if there is a style you can learn nearby your home. There are so many different styles to learn that there might be something for you, and you would meet a lot of new, active people who might have interests in some other outdoor activities.

Other than that, you can look into finding some sort of club or... I dunno, a gym or something similar where people go to do sports like that. I know they have them, and I don't think they are all expensive (though I am sure some are and I don't really know anything about your area). Have you tried looking at websites for your city that might have some sort of similar group? You could even try Craigslist or something like that XD
