Cambridge City Park, with Nat'l Guard Armory in the right foreground. Behind it is the city pool, and across N 9th St is the main baseball diamond. The tennis courts were moved a block North, and the old ones are now basketball courts, with a sand volleyball pit in the "bare spot" at the extreme left side of pic. The running track around the high school football field is just visible at the bottom.
