Back in the old days, all the big bore drivers, we would get together for dinner the night before the race, drink and get s---t faced, stay up till 1 or 2 am, get up at 6 am eat brkfst and then race to the track for first practice and qualifying.
Thankfully my carburetor guy was older and did not participate. His magic with jetting was so critical.
When one is young and dumb, as we all were, one can do those sort of things. The trip back home was the most dangerous as we were all so **** tired.
