Tennis Meetup

How can I meet people in Sacramento?
I am going to be working in my godfather’s law firm this summer in Sacramento, and will be living with his family. I live in Seattle, and am 18 but don’t know how to meet people in the new town. My godfather has a daughter roughly my age (One year younger) but she is going to be gone for most of the summer, leaving me alone in a big city.
Any help on meeting other people my age would be great, I am fairly active and have a lot of hobbies (photography, tennis, soccer, hiking), but sites like meetup.com seem like they are just for older people.
Appreciate the help!
There are definitely a lot of things to do here. If your looking for active things to do you can join a rec sports team:

or another summer program. I know they have tennis and soccer groups you can join. Otherwise Sac has concerts in the park and a lot of other activities.
Hope that helps
