Welcome to the club!

This is also my first year, so I identify completely.
I agree whole-heartedly about the mentor thing. I am lucky enough to work with two other guys (in my other life) who are also referees. One has been at it for 10 years, and another 3. I think that is a good mix because one has the experience and is on varsity level, and one is not that far removed from where I am!
Also, I did purchase the 2-man mechanics video someone mentioned. Although not the greatest, I did find it helpful.
And one other tip- read this forum! And read the rulebook over and over!!

I'm amazed at some of the guys who have been around for a couple years and do not know the rules...
GOOD LUCK!
