Haven't really seen it here. Most leagues are full before the season starts. Most I've seen is one vacant team, or a couple of teams with 1 vacant bowler.
Our leagues are usually around $20, with $11-12 for lineage, $0.50-1.00 for secretary, and the rest goes to the prize fund. I wish they were cheaper, and I wish they would be more flexible with the 35-36 weeks, but most of the houses I've seen are full just about every night of the week.
