Thank you all everyone is so helpful. We live in the middle of nowhere, drive 3+ hrs to the airpirt or out of yown regularly so 6 hrs or night driving is no big deal... 8 though takes it to the next level. DH asked about 99 vs 5 but I wasn't sure, any specific input there?
Not a huge difference. I like 5 better myself and I think that the speed limit is higher on 5 making it a faster trip.
