I have volunteered at the Barbasol. Unless things have changed substantially, I can understand why they struggle to get volunteers.
I think you mentioned previously how disorganized it was the first year, and I don't doubt it. But I know lots of people that have volunteered for two or three years now, in a number of capacities, and they really like it, but getting 1200 or so people to volunteer for four or five days is a tall task. I am a prime example, I love my club and the event, but hell, I also have a full time job, I can't take off several days just to be a scorekeeper or monitor the driving range.
