There were a bunch of Kevins, and my last name is Kolkmeyer, So Kolk was my nickname, then back in like 99 or so when I signed up for my first email account, they wanted a number, so I just picked 1. So its been Kolk1 since. At one point on my camaro that I built for drag racing, the plate was KOLKWON, which I then later put on my corvette.
