We have also heard great things about KU's camp. My son has played in the HS fall league that KU runs, but never attended the camp because we were always still playing baseball till that week.
Everyone who goes has good things to say about the camp. Coach Price is doing a good job in bringing KU to the upper half of the Big 12. He is great with the HS kids who participate. Fall ball ran 6 weekends and he was in the dugout coaching every single weekend. The field is BEAUTIFUL!
I did hear that there was quite a representation from California last summer at the camp. Coach Price is from CA and attracts many talented players from the west coast.
As far as other coaches go, call the school and ask who has attended in the past. I know many coaches from KS schools attend, but they were smaller schools.
