Couple 30-40ft down rails with a pretty good run in at the Seaport in Boston about a block from Sal's Pizza in a commercial plaza, it's completely dead on the weekends in the winter.
If you get a good dumping, you can build some sick features at Boulder Park apartments in Nashua, exit 8 off Rt 3. 5-15ft boulder drops, lots of shelves in the landscape to build 20-30ft kickers, and pine trees to bonk.
