Yesterday my friend Dave and I carpooled to CalTech in Pasadena to see a lecture given by the Skeptics Society.  Dave had never parked in the CalTech parking lot, so I directed him to a spot at random.  Inside the full auditorium, we ran into our friend Julia, who we had no idea would be there as well.  When we walked back to the parking lot we found out that our cars were literally parked nose-to-nose!  With 300 seats filled, I guess around 200-250 cars were in the lot for this lecture.

What are the odds?
