Replying to SICK urban in boston

theres some dope urban rail in boston, to be specific for whoever is familiar with the city its right by the fens, some park right by fenway park, its on a street actually called fenway street or something, its by a slightly steep hill and its a really long rail with a series of down flats, excepts its not kinked, its very mellow so its like a continuous down-roller coaster rail, it would be sick to hit, and im pretty sure its been done cus i was there last weekend and there was a little drop in ramp and it def looked like someone hit it
i hope someone knows what im talken about
