My '22 just did a Stanford Holiday 80 camp for pitchers and catchers. Instructional focus, capped at 80 players (hence the name). Two 5-6 hr sessions, well run with good coach and player interaction, and terrific instruction. Offense was 3-4 guys at a station with a coach or player present (mix of Stanford and local schools). Good option for those on the west coast. Mostly 20s and 21s, as one might expect.
Despite my avatar, I was quite impressed
We are planning to do Duke next summer.
