What do you do with your middle school age children on School holidays?

My son started Middle school this year. I am curious to know what other working parents in the Westminster area do with their children on School holidays. The before/after school program we used is no longer available to kids beginning at age 12, and we had not given these school holidays a thought until now.

Are there any sports clinics at the local facilities, or are there Day Camps at the college or anywhere else?
