just want to add, that Treks advise about entering the routine number for your PD in your cell phone is a very good one! There have been a few times when I have had to call something in while driving and while it isn't a 911 emergency is something that should be reported so I can just flip to my address book and press dial.

I have 3 towns that I drive through back and forth to work every day and I have each of those numbers in my phone and have had occasion to use each one at least once to report stuff
