That depends on whether you want to stay up late and enjoy some beverages and more socializing. It is entirely up to you, but the vast majority of participants stay through Sunday morning; almost all who are camping do. To answer the question directly, the raffle should be over by 9:30ish. In years past it would drag on until midnight or so, but the last couple years we've tried to get it going earlier and work through it a bit faster. It really all depends on when we can everyone off the trail and fed, how fast our em-c works, how many prizes we have (which usually fills up two trailers and spills over), and how closely people pay attention to their raffle ticket numbers. It's amazing year after year that we have to call the occasional number 4 or 5 times and stilll don't get anyone to answer up. So bring your flashlight (and MONEY!) to the raffle!
