While I am not there due to unforeseen emergency home repairs, I will tell you from the last two years the pilots meeting is more for a reminder of rules for the flight line, who a couple key people are I.E. who is in charge of the flight line and first aid (I was supposed to be), and basic info for the day. Otherwise follow the rules by the entrance to each flying area and you will be ok.
It was a little more then that. I was there. I've been the First Aid lead for the last two year and would have been this year but home repairs forced me to stay home this year. All you have to remember is this. Follow flight line rules, keep props off in the build tent, and fly smart and you will be ok.
