It always seems the dump trucks/logging trucks and other micropeen-mobiles (giant diesels) that swerve when trying to pass/get pissed and try to play butt-touch when you get by them. Had one guy do this last year on a ride with Derek and Gasser (I think?) driving a 2x trailer log truck that was fully loaded. Derek got by him and the dude shot up to 100 in the straights, cutting the inside of oncoming lane through blind corners trying to catch him.
GoPro will be with me and recording on every ride now so when shit heads pull stuff like this, police will become involved.
