Parking shouldn’t be difficult: there’s no ticketing on Saturday afternoon nor all day Sunday, so everyone can ignore the 2hr limit and park for free on Mass Ave near the Center on those days. On Thursday and Friday, it will be best to park on a side street like Palmer, Wyman, or Allen St., none of which are ticketed. Another close option is the free lot at Spy Pond Park on Pond Ave, just across the street from the center.
