In Worcester, go to the Texas Roadhouse, in that plaza theres a dfdfd without a donkey dick and a much more realistic dfd that a bunch of boarders hit.
Also in millbury at the shoppes at blackstone village, theres a nice rail.
Blackstone valley regional high tech school has a huge down rail outside of it, not the main enterence, but i dont know if youve ever been there. Also try the train tracks near there.
