almost every town has it’s own main street. you asked where the dealership was, he told you it was on main street in the town that you acknowledged that you knew it was in. obviously main street in buffalo is different that the one in e.a. and orchard park and hamburg, etc. most non-idiots know this.
anyway, in reference to the 400, take it to the rt 20a/16 exit, go right, that is main street in e.a.
also, i think most do not consider e.a “the boonies.” it certainly isn’t the big bad city that buffalo is, but it’s not hickville.
