Another Chicago tradition

Back in 2008, I was in Chicago to look at houses and I stumbled on a
naked bike ride to raise awareness of the United States's dependence
on foreign oil. Last night, on the way home from the midsummerfest, I
stumbled on the ride again, twice. The first time was accidental and
the second was while deliberately trying to AVOID the ride. Maybe next
year I should just plan to ride.
