you're, reasonably enough, worried about crashing your bicycle while drunk...meanwhile...me and other idiots used to pretty much do this, but on our motorcycles....as stupid as it was, it felt amazing...you feel invincible (until you crash)
funny enough, I smoked bud and tried to do the same thing and was terrified....didn't make it out of the neighborhood....actually abandoned the bike (like two houses down, but still '>.>)
