59/60 and just got the 5 hours played achievement. Going to go to bed, leave the screen up, and wake up hopefully to the 10 hours played achievement and the badge :)
The sixth challenge is by farrrr the hardest. If you try to race to the end, you will lose. Period. Instead, what you should do is stay BEHIND the cop cars -better yet, let them go off your screen - and when the helicopter comes, dodge out of it's bombing range and literally stop until it finishes bombing. It took me twelve minutes to complete my 8.5 mile run, but definitely worth it for the least awarded badge on Kongregate.
