I am not one to drink and ride(i don't really drink at all anymore,would rather eat those calories)..
But back when I was in college we would bike to happy hour and then bike home, always interesting! and if I remember right, we didn't do it to many times after the first time or two.
But on another note, what about those wine tours in Italy and Napa,CA? Where you bike from winery to winery... Wouldn't stopping for a beer be essentially the same thing?
