We live outside a very small town (located in very rural, mountainous environment).
The majority of teens in our area are into horses & 4-H, hunting, fishing, camping, skiing (downhill & cross country) and other outdoor activities. Many workout at the local fitness center (they get significant student discounts). Fair week and rodeos are BIG, here!
Being a small community, teen jobs are minimal (a lot of kids "work" on their family ranches and farms). But, the business that do hire teens, try to hire as many as possible. Businesses give teens the use of their locations for fund-raising car washes during the non-winter seasons.
There's a group of kids from immigrant families that go around neighborhoods, at the beginning of each snow season and are hired, in advance, to shovel snow for folks. They know which homes need to be cleared before the school hours begin and which can wait until after school. They do a great job and have sparked other kids to do the same. This is to raise money just so they can do things without asking their families for money (their families can't afford much in the way of allowances). That is initiative!
A lot volunteer at the local assisted living and nursing homes. I know of 3 that volunteer at the library, 5 at the local food bank and 7 at a local animal shelter.
Volunteering is very big in our community. I think it is a great thing for teens (well, for anyone, actually) to be involved with. By focusing on the needs of others, it lessens the "it's-all-about-me" feeling that, I think, many teens have. They become part of the bigger picture and learn a hell of a lot about other people.
When some local teens wanted a specialized recreational area, they got together, proposed their plan to the city and raised the funding to make it a reality. They help maintain it (volunteers empty the garbage barrels and raise monies to pay for a pop machine) and have been very vocal regarding the fact they want it to be a safe place to hang out.
I think teens need to do more about working towards and for their recreational wants instead of just having it all handed to them. Rec centers are fine, but if the teens aren't expected to help maintain it and keep it a healthy environment, they don't appreciate it as much.
