Bike Forums - new biker here

hey, guys, im 21 and from queens new york. i wanted to get a mountain bike to ride around at night for excercize and such. i just got 500 dollars from all my coins haha so i decided to blow it on a marin b-17. however, im not quite sure what model it is. i got the bike new for 550 and thought it was a great deal and the guy was a total salesman. its a matte black with 01.1 down frame and its a 14". it had marzocchi forks n stuff with disc brakes, probably the best bike i've had, besides my trek fuel that i had a while back. anyways, i was wondering if the bike is good for the money, and if its good for riding around the streets doing some mild trails. and does anybody know good trails in nyc?? thanks a bunch, i look forward to riding and keeping in shape till im old :D
