Of course, Stingrays.
GAPSS, lots of competition. Must attend.
The Columbus NSA has always been a good competitive event. This next year I believe it is going to be USSSA and still run by Mike Craig. Mike always puts on a good tournament with good competition. A must tournament. Usually an early to mid-June event.
Last year was our first time at Sluggerfest (14U) and there was excellent competition. Patti is changing some things this year to make it more family friendly. It should be on the list.
Never been to the Toledo Tune-up but have heard good things.
One that usually flies under the radar is the Delaware Jug Tournament in late May (I believe). Not a huge tournament but usually good competition and a good, hard working staff.
There are some good tournaments with good competition in Western PA. We used to attend the Hornet Early Bird in Ambridge (just north of Pittsburgh). Great competition and a hard working staff.
