a very helpful resource map
if you want to lose stars fast, hop into the subway tunnel. an entrance is found at the intersection of uranium and frankfort ave, just north northwest of middle park, on Algonquin island (the middle island). you can use the map above to pinpoint the location. you can get away from 6 stars unlocking an achievement (you might want to bring a car!)
a turismo (ferrari) dealer can be found at the intersection of Pyrite st and Bismark ave, east of middle park, on Algonquin island. it has like 8 ferraris but youll get a star when you steal one. who cares though! theyre ferraris
An nrg 900 (fast motorcycle) dealer can be found at the intersection of Lemhi St and Sacramento ave at the northern section of Alderney (west island). like the ferrari dealer, youll get a star but can lose it easily when you jack it
a skate park can be found on the west coast of Algonquin, directly west of middle park
IMO the funnest jump in the game is across a river. it is found on alderney directly east of Mahesh ave. its directly west of the skate park. mahesh ave is in an L shape. start on the western part of the east-west portion of the street (start at the corner). gun it to the jump and youll make it with a decent car
