There are 3 parts to this challenge. The first two parts are easy, just beat them in a couple skate competitions. But the 3 part may cause to be a litttle tricky, if you dont know what you are doing... You will start out on a roof, from there you jump off a kicker, and grind a wire, than a ledge, jump down, grind a flower bed and jump and grind up towards the general direction of the skate park, here's where you might get confused. Keep grinding it, all the way around, until you are facing the direction that you came from, now you will clearly see where to go. Grind the benches and other things, and manual to the ramp. You are Done. Achievement Unlocked!
