On June 28th, DCR kicked off it's new Park Passport, a stamp book with stamp stations placed in 76 parks across the state (15 parks in the Boston area, including John Paul II, Castle Island, and the Southwest Corridor). Each park has a different stamp, so you have to go to all of the parks if you want to collect all of the stamps. When you complete any one of the 5 regions, you can use the completed passport at the regional office (starting August 15) to receive a t-shirt with the stamp pictures on it for that region.
