I feel your pain.
Somedays there is nothing to do and no where to go. Just take a trip up to Walmart or the nearest mall to waste some time. Usually for me if i go to these places I end up running into someone I know with something to do. Then from there driving more to wherever my friend wants to go.
I live right next to a major city (Pittsburgh). Cruising down there and seeing whats around is fun also.
Also when anyone wants to do anything I ALWAYS insist on driving to those miles in
