Infielddad is indeed dead on correct, except the CPL is a "for profit" league as well. Our league, the Valley League, is nonprofit,as are several others. (MLB only gives grant money to nonprofit leagues, but their contribution amount hasn't changed in many years.) The "for profit" leagues are known as the "Beer Leagues" as the privately owned teams make significant money off of alcohol sales. In the VBL, alcohol is taboo at all ball parks.
I've been told the NCAA has some type of supposed limit on the number of summer games, but if there is such a limit, it surely is ignored. We play 44 regular season games, then playoffs start around July 24 and the season is completed by early August, which we like. After 44 games, and a full spring, these guys are tired and like to get home for 2-3 weeks before starting school again. The travel in our league is comparatively short-our longest trips are two games that require a 2-2.5 hour drive but most trips average around 30-40 minutes, and as for our team, we have 4 teams within 25 minutes. The leagues with the long trips do a nice job marketing those long bus trips as the "minor league experience", but I'll take our short hops any day of the week. I can't imagine a 70 game schedule plus playoffs-the divorce rate among GM's in those leagues must be high.
The top talent seems to be spreading over more leagues, with the Cape remaining the top dog target but it has it's issues too-beach traffic can really jam up the roads and many Cape Cod teams have a reputation for quickly unloading players that don't meet performance expectations-some pretty good players have gotten off to bad starts, and were released, only to find rosters in the other leagues were full.
It's worth checking out the various leagues so a player knows what they're in for-if you want to see your home bedroom before going back to school, the 70 game leagues probably aren't going to much work. Many leagues now charge fees to players but some don't. Some charge for housing, some don't.
Summer leagues are a lot of fun for players and fans, but as is true with picking a college, a little homework helps.
