[Kenwood] going on a trip, using APRS is there a special freq?

[FireBrick]

I got the Kenwood D700A working in the truck.
I got a Garman GPSII
I got the connected even.
But I have no idea if there is a special frequency/channel that is most popular with APRS 
types.
I won't be transmitting much, I can barely walk and chew gum at the same time so driving 
and chatting is out of the question.
