Seeing as how most of our friends are either married or seriously dating, we opted to have a co-ed bachelor/bachelorette party.  And what better way than to partake in one of our favorite activities?  Skiing for 4 days at Mammoth Mountain Resort.  We rented a huge condo where everyone could stay at Snow Creek Resort, went skiing during the day, and then hung out and played games at night.  We had an absolute blast.
