I agree with Richard. If you take the long term of more than just a couple of deaths over the last 2 years and look at the ones you don't know about or that drinking was a factor and it was just not stated then the ratios go way up. I can remember incidents over the years and there were so few non drinking incidents I can't remember the specifics of them. But there are enough of the drinking ones that I can tell you that I was there many weekends where more than one accident resulted in body bags and torn apart families. You know my personal rules about drinking and driving. Driving is for daytime and campfires are for drinking. I learned that lesson the hard way and came closer to being a sastistic my self.
I rode banshee's with a bunch of very fast riders, kinda of how I learned. It was like racing motocross at top speed. After awhile I heard that some of the guys were taking "safety stops" then riding at full throttle passing and being passed by me. I learned what a safety stop was and that was it I didn't ride with them anymore. Nice guys but I am not putting my life on the line to ride with someone who is messed up and it cost's me. i have had my share of accidents in the dunes but all of them have been my stupidity not from being intoxicated or inexperienced, they were screwups just that plain and simple.
