I do ok if I can sleep and
only if the car seat is comfy (like my current car). But when I say STOP to use the restroom, it means soon. It slows us down but that's the only way we can do it.
We haven't had any really long trips in awhile though, last time was summer of 2007 when we drove to N. Wisconsin for our summer trip to the north woods (7-8 hour drive).
I'd like to do a road trip and see lots of places, sort of like AMN did a couple years ago.
It's hard for me to take long stretches of time off work though.
We should go to Texas to see my BIL and his wife in Austin, since she can't travel anymore. We could do some extra stuff while there too. We might have to fly down and rent a car for any extra siteseeing.
