... while riding my bike?
Most of my friends live about 2 miles away. The first mile (on the way home) I use the sidewalk, then go through campus. The second mile I'm usually on side streets.
I'm not worried about going to happy hour and having 6 beers (thus technically being over the limit). Last night I don't remember any of the ride home, and I have 1/2 a bag of popcorn which I don't remember making or eating.
