They had too much to drink.The guy wanted to take a girl for a spin just after 2 this morning.When she didn't want to get onto the bike,her friend wanted to go with and when they told het she should put on a helmet that was in the one guy's car,she apparently didn't want to.He wore a helmet as far as i know,but even that didn't help.The bike took out a chevron board from the side (I think he wheelied into the board because there's no brake marks on the gravel either).
