I've got a hint,
if you want to get from place to place and score some points, just hop into the air and when you land, do a manual, when you think you are going to fall, hop again and this will prevent it
Down town Rio
in the rio de jeniro level (you don't have to be on cereer)when you start, hop over the left rail and keep on going forward until you come to that hill going up, go up it and go up the quarter pipe infront of you, and keep to the right!
When you land, after about two seconds of going across, jump up and grind the rail above you, keep your finger down on triangle, and try not to fall over, eventually you will find yourself in down town Rio de Jeniro! &
