I have a segment set up on the park by my house. Its a half mile loop with a nice straight, some kinda twisty bits, and some uphill on the other side. Its good for mindless laps at lunchtime. I'm a novice rider and my KOM was like 2:01 or something like that.

Some dude came in and set a 1:35 on it on Friday. I mean, come on man. Did you honestly go out of your way to get that KOM on this park? Oh, wait, you have something like 200+ achievements. /sigh
