Nearly a year ago, while riding practice at my favorite track on a Saturday, one of my co-workers showed up to ride. After several laps I took a break and rode over to his pit to chat. He was drinking beer. We chatted a while and he kept drinking. I mentioned that he can't ride now that he has been drinking. He became irate and yelled at me to mind my own business. Once he rolled out on the track, I informed the owner that this guy was drinking. My friend was immediately black flagged and then became extremely angry with me for being pulled off the track. Since then, he refuses to acknowledge my existence. I DID NOT enjoy having him removed from the track, but thought it was in the best interest of everyone at the track. I firmly believe that the mixture of alcohol and motorcycles equals death or injury. I tried to explain tactfully to him that it would be better if he had his beer AFTER practice...not during. I've lost a riding buddy. Oh well, good riddance. I'd rather ride alone than with a drunk.
