First suggestion is to utilize the "search" feature on this forum. I am pretty sure most (if not all) of you questions will be answered. ;)
Otherwise, main thing I want my riders to do is "listen" to me and enjoy themselves. I will give a quick "briefing" before we head out... I'll let them know stuff like:
1 emergency button locations
2 if I have "radio" chatter...please be quiet, as I need to listen
3 ask questions at appropriate times (see 2)
4 shadow me, unless I instruct otherwise
5 use common sense and good judgement
6 etc etc etc....
I play Cops N Robbers for real...and its fun.
