Stockton has the Bowling Outfitters Classic @ Pacific Ave on Tuesday nights, but it's an set team league I think. You would need to find a team that needs a bowler that would accept you. Very high level, I think the league average is in the mid 220's. If you contact Dave Bolles at the Pacific Bowl Pro Shop, he would know more about availability.
There is a Mixed scratch league @ Pacific on Thursday nights, 5 person teams, somewhat mid level as far as skill goes. Jim Dinubilo has been the secretary of that one for a while so he would be the person to contact about it.
West Lane bowl has a men's classic scratch league on Thursday night, but again, most of those teams have been together a while, so you would need to contact Ron Lubin to see if there was a spot open.
If you don't need scratch, there is a very high level handicap league at West Lane on Wednesday nights. The Budweiser Chase has sponsorship and the pay off is very nice. High skill level league, trios. It's a handicap league, but the handicap is 90% of 250.
I can't think of any others right now, but if I do, I'll let you know.
Manteca is about 50 mins. or so away, that's if hwy99 has no traffic. Maybe.... I get off at 5pm from the hospital
I would love to bowl with those guys/gals in Cooks League, but I'm not in the same breath as those guys and gals. I do bowl, have met, and know some of those guys - cool dudes. Also, I met Todd Adams (Todds Propshop) through JustRico recently, I think T.A. bowls in Cooks league too.
What about Stockton? any Scratch leagues there?
