You have the channels & earbuds...you're ready to go.
I did a trip several years ago from TX to Chicago to
Portland, OR....round trip...with my earphone & handheld
listening all the way. Ya gotta know what's going on.
For the "curve" get the camera ready. Fun trip.
Might want to add the major cities along the way. A GPS worked great on my cross country trip. Needed a suction cup mount for the antenna to get a signal. Placed it on the window.
