I can't get enough height with a wall ride to get on top of the fanboat garage roof. Is there an easier way to get on the roof? I just can't ride the wall high enough even to grind the lip of the roof like the walkthrough says. Please help.

Thats exactly what I need to know !!!

lol, many have problems with this one! as i learnt in the previous dave mirras, if you cant do it forwards, do it backwards!

so, instead of going from top to bottom, go frmo bottom to top..just keep jumpin and re-grinding, and youll have no problems getting up there!

when you do reach the top, just stop, turn round and grind down...there you go, challenge over, wasnt so hard was it?

Yes, but how do you start at the bottom ?

just head on over to the island you have to grind to from that roof. head down the left side of the level at the start. when you get to water, turn right. at the end of the road, there will be a bridge with a gap in it. jumping the gap is much harder than it looks, so don't worry about it. jump off the bridge as if you're jumping the gap, but quarter turn to the right, and you'll land in shallow enough water to get you to the other side. there's a quarterpipe on the left, the first jump to the right of the quarterpipe is where you need to go to. just get on top of the jump (the jump has a flat part on top), and face the fanboat garage. you'll see a line you can grind that ends at the pole right in front of you. jump on to it and grind all the way to the roof. just link together a combo of grinds and keep jumping, you'll get enough speed. when you get to the roof, turn right back around and continuously grind back to the island. you'll kick yourself when you see how easy this really is.

That's Quite hard!
My biker always jump away from the string!

i just cant get enough speed to reach the top

simply keep jumping and re-grinding to reach the top of the roof...

Well you have to go up the bridge. Then break the window and jump through some fan boats. Then smash the next window and wall ride to get up to the roof. Then find the wire and grind down it.
