I feel very fortunate to have discovered just such a travel "league" (actually, more like a series of scratch tournaments). The organizers set up 12 events at 4 different bowling centers. Each event has a different Kegel or USBC pattern, and a different format (singles, doubles, match play, bracket, total pins, stepladder, baker, etc). There are two events per month. Entry fees range from $45-$65.
The only downside for me is all of the events are Sunday morning at 9:00am in another county 75 miles from home. I was not aware when it first started, and missed the first two events. Now, I am hooked. And, the turnout has increased each week. The next event, a match play championship on the 2012 USBC Masters pattern, is already booked.
Win or lose, this is great fun and a welcome challenge. The folks that do not take advantage of such opportunities, whatever their excuse, are missing out.
