Bustin Billboards Trophy
Tear through 500 billboards.
Billboards are another of the game's objectives, however they aren't as common as some of the others. Upon finishing the campaign you should have around 50. The rest can be torn through in the Quick Flap billboard game. I recommend the 3rd event to get this trophy done as quickly as possible, because it's a relatively simple track to follow and still yields around 50 billboards on each attempt.
