The monthly SPARKS newsletter lists many other non-regular events that don't have their own webpages, events like:
- Ski Trips
- Bowling
- Volleyball
- Wallyball
- Laser Tag
AND MORE!!!
But I guess you will have to join to find out about those, hint, hint! (Actually, click the link on the upper right of the homepage and you will see information about how to get three FREE issues of the newsletter.)
