I've been road biking since 1998 and have put in about 80,000 miles and I had my first confrontation with a motorist. I was going down an old country two lane road near Grand Rapids, MI this evening and this knucklehead and his buddy in a van come up next to me and lay on the horn and they both yell right in my ear. I hear them laughing and gather myself and immeadietly flip them the bird. About 1 mile down the road, guess what I see? They are pulled off the side of the road. Without hesitation I pull up to the drivers window and start going off on him. I scared the crap out of him and he almost had a heartattack. He immeadietly gets out of the van and starts off on me. He tells me to just ride on before something happens. So I plant my elbows on the handlebars and just laugh. I start yelling at him and tell him I could have broke my neck. He keeps saying what are you going to about it. His buddy keeps telling him to get back in the van. I was about 2 feet away from the guy the whole time as we continue our verbal assault. He was a pretty big guy, but I'm no small guy at 5' 11" and 215 lbs. After about another couple minutes of this I just decide to ride on. It was a work van with the company name and phone number on it and I know his name was Dave. I wasn't thinking clearly, just seeing red. If this happens again I will get a picture of the van and license plate with my phone. After about 3 years of living out here this is the first time anything like this has happened to me.
