Thanks for the suggestions! Somehow I'm not hopeful the wife won't notice having to stop an extra 2-3 times to nurse the baby... She might also get a little antsy when we don't get to her parents' house in the usual 12 or so hours. Maybe I'll just wait until she falls asleep and claim I 'accidentally' took I-10 all the way to Pensacola, then 'accidentally' went all the way back to Jacksonville before going back to I-75 again; then if she doesn't put her glasses back on and look at a road sign, I'm home free!
Or maybe not...
