Pre-Game Communication

[CountTheBasket]

I struggle with this because I do not want to step on anyones toes so I wanted to get an opinion from anyone who has one. When I'm the R on a game (HS varsity) I like to send out the standard email/text/phone call (whichever seems appropriate) 24-48 hours before a game to be sure everyones on the same page with time, location, level, etc. However, at what point should the U1 or U2 step up if nothing has been recieved from the R. Maybe I'm over thinking the process, I just don't like to start out on the wrong foot with an unknown R if they're going to feel I'm doing their job.
