You can try synchronized swimming if you can atleast swim a good 200 yards and be able to take some time out of your personal life. There are many places you can try synchronized swimming like right here in SLO. Or if you live in southern California, you can go to the YMCA and do synchronized swimming until you are an experienced synchroian and then you can join a club team. Now if you live in northern California, there are many synchro teams that are willing to envite new sychro swimmers. Just keep these two things in mind, be willing to take risks and just have fun!
