well..he didnt say bump from roof or get on roof w/ car.lol
out of about 15 trys,my best was 53 ft hight and 223 ft distance.
i always hit the middle of the sign and have to bail b 4 crash,or i just crash =-p
im guessing its about a 60 ft bump,and 230 in distance..kinda hard from that small of a bump.
