I may make Margaret drive during some of the scarier bits. She's younger and less experienced...but a better driver. ;-) Part of this is just that I have trouble judging distances, which means heavy traffic involving lane changes really, really scares me. I'm fine otherwise...even enjoy driving. Like that trip to northern ME last summer was fun!
I think most of the trip should be pretty decent traffic. I get nervous about trucks which is why I dislike driving after dark. Other than a couple congested areas near cities, my trip out was pretty uneventful.
