I was on my way to work yesterday morning traveling East on the Boll Weevil Circle (Gotta love you're main road being named after a bug) in the left lane. I was in the proccess of passing a F-350 when I notice the driver has a phone to his ear. I actually backed of just as he started to come over on me, forcing me toward the left edge of the road. I Pressed the horn button and he literally jumped back in his lane. I think (OK, hope) he pissed his pants. He was waiving and obviously very sorry for the infraction. Maybe he'll remember to actually drive when he's behind the wheel of a vehicle from now on. The WOLO Bad Boy horn is extremely loud and I'm glad I installed it in the fairing of my XC.
