Relay for Life 
Yeah, I did that this year for my university.  For those that do not know, the American Cancer Society puts this event on around the world to raise money and awareness for the prevention and treatment of cancer.  I must say it was a pretty profound event.  One of the women who helped run the event was a cancer survivor, along with a handful of others.  At the very beginning, they were able to do a "Survivor Lap", where they got to walk the track by themselves.  A handful of the younger ones were crying through this.  Following that, people from every different organization would be on the track in shifts.  Eventually, we did the premiere event of the Relay: Luminaria.  The Luminaria was a segment where a series of illuminated paper bags were placed around the track.  Every bag was for someone connected to a Relay participant who either survived or passed away from cancer.  Again, lots of tears being shed here.  The rest of the night after the Luminaria, however, was mostly just fun.  Each team had some kind of activity or food they were selling, so on their break different team members could go around and browse everyone else and hang out with their friends.  Someone started a massive line dance to one of the awful songs the student radio DJ was blaring.   Of course, some versions of Relay are infamous for continuing through the night and into the morning.  This Relay was one of these.  I started setting up at 4am, and finally cleaned up and left with my group when the Relay ended at 7am the next day.  I was so damn tired, but it felt great that we did it.  As a school, we raised over $44,000 toward cancer.  To put that into perspective, last year the university only raised $20,000.  Imagine how much money will be going into cancer research if we have an increase like that every year.
