Old NOOB looking for advice

[mplagrow]

I've been reffing for some 20+ years, but since I've been connected to a private middle school system, I've been doing almost exclusively 5th-8th grade games, to the tune of 60 games a year. I've attended one reffing clinic, maintained state licensure, and reffed probably a half dozen high-school games in that time. I now have a regular partner who is young and gung-ho to start doing more high school games. We've been working together for about two years now, and have pretty good chemistry. So starting tomorrow we're picking up some JV and Frosh games. I was hoping some of you vets would share some good advice for someone like myself who's going to have to adjust his game from grade school to high school.

Thanks!
