Just in time for my upcoming U2 pilgrimage with Joel, I came across a helpful how-to article on road tripping, courtesy of The Morning News. It's a fun read with some good tips, like this one:

Driver Controls the Music
Passenger gets two vetoes per three hours or 150 miles, whichever comes first. No exceptions.

Not that Joel and I should run into that problem. We already have a listening strategy mapped out -- 10 hours of driving, 10 U2 albums.
