When getting a job or playing a sport, you want it be where you live in Denver, right? Well it's usually for the convenience and not having to drive all that far. However, sometimes you're not lucky and you'll have to drive a little farther to get what you want.
You can usually play volleyball in your school, but if you want to play outside of school, you may have troubles finding a league to play for. There are probably a couple leagues at least in Denver to play in, but how close to the city you're in will vary. I mean if you really wanted to play, you could drive the extra distance to go there or you may have to convince your parents to take you if you can't drive.
For example, volleyball is getting more popular, but isn't really that popular yet, so if there is a different sports league near you, just try it for fun. To find Denver volleyball leagues or any place really, just look in the newspaper, watch for flyers at school or posted around the city or state. When looking for Denver volleyball leagues, you can check out some of local parks, which have both leagues and just a place for you to play. Also, some of them have indoor and outdoor courts as well. However, you may want to try a YMCA that may be tad bit more organized than a park would be.
However, if you can't find Denver volleyball leagues and you don't want to try another sport or drive, you need to keep your skills up for the following school year. You could do some volleyball drills if you had the place for it and if you were a setter, you may want to try going to some volleyball setter camps on the off season.
