I am a resident of Upton and wanted to share a summer camp/program with your readers.
Forekicks in Marlboro offers an abundance of athletic classes for kids ranging from 18 month 18 years & beyond. I live in Upton and Forekicks is only 15-20 mins away. My son is 4 years old, has taken 4 sessions and absolutely loves it. The program is very well organized with a great group of coaches. 1stclass is free (mention referred by Sean Menchin).
Admission is rolling, classes started last week.
Soccer ** highly recommended
