I was riding up the CCT today and came slowly up to a guy, we were doing about 17 mi/hr. I was coming up so slowly on him that I rode 2 ft behind for a while getting a bit of a pull effect. I said hey "do you mind if I ride your wheel a bit" he said yeah.. then almost immediately he spit on the right side and sprayed me! The spit wasn't AT me , and the main part of the lugie did not hit me... but I got the point and backed way off. He wasn't spitting before this, WTF?
