I skied in college, mostly for the girls, parties, and free coaching from teammates. I didn't ski another tournament for years after graduating since it was no longer a team event, I didn't know anyone, and I'm nowhere near advanced enough to hold my own.
The next tournament I got into was a barefoot one since the organizer was giving (and still gives) free entry to anyone if it's their first barefoot tournament, and gives lessons the day before for the price of gas. I had nothing to lose by trying it. There was a huge potluck the first night, and I met a couple cool people there. We camp out together, have a fire, have some beers, it's a good time. I now do that tournament yearly.
If there was a three event tournament nearby (within a couple hours) that either was offering free lessons the day before or free entry for first timers, I'd try it out (who wouldn't?). If the people there were welcoming and I got to know some of them, I'd be interested in coming back. I'd be even more interested if there were a handicap in place. I think Horton's idea of taking five tournament scores in the past year for a handicap would be too many to interest me. I can't see myself ever doing more than three tournaments a year (that's a lot in a short WI summer), so taking the past two scores would appeal to me more and incentivize me to entering two other tournaments.
