I remember playing YMCA T-ball when I was young, and how great it was as a team experience. Now my boys regularly participate in YMCA youth sports such as soccer and baseball. Some other sports I know of offered in season are flag football, basketball and even golf. YMCA has summer day camps.
It's not too expensive to get involved. Members pay less. Sibling discount. Be sure to check into the scholarship program for low-income families.
The front office staff has always answered my questions whether in person or by phone. The coaches are all volunteering and seem to really enjoy working with the children. Good experience for all involved, especially the kids.
