almost in a car wreck

I live in Atlanta..was going down West Peachtree St., a one-way road and some asshat in a new truck decides to go the WRONG WAY FOR A SIGNIFICANT DISTANCE to get into a particular parking lot. He was in my lane coming right at me and SWERVES at the last second (felt like I was playing chicken or something). Needless to say I had to lock up my breaks, back end fishtailed a little but I was able to get it back into the lane, and luckily no one was right next to me so no wreck happened. I held my horn for a good 3 seconds afterward and just wanted to get out of the car and give the idiot a swift kick to the rear.
