I think I may have been the one that spawned this... I did make a joke or two about this. I'm the only one around I know that's done this, but I'm sure it's done a lot. I also know when to call it quits. If I thought I was endangering myself more by riding drunk at 3am than I am by riding sober with the normal mid-day traffic, I could easily walk down the sidewalk. Infact, a lot of the riding I do around town is in parking lots, on sidewalks, and the occasional low-traffic road. I'm an extremely safe person in general and wouldn't do anything beyond what I feel in control and comfortable with.
I'm not trying to get any arguments going and I don't approve of riding a bike beyond the limit you can handle. I DO, however, have a problem with driving a car while or after drinking.
