The 7- to 10-year-old champions, red shirts, and the 11- to 14-year-old champs of the Department of Parks and Recreation’s boys summer basketball league show off their medals July 29 at the Veterans Memorial Park courts on Bull Hill Lane. Both teams slogged through a tough schedule of games. Supervised by recreation program coordinator Tom Conroy, the league, which aims to keep city kids active, just capped its 18th season.
