My kids are all grown now but we moved from West Palm Beach, FL to Oklahoma City when they were very little...over 2500 miles and two and a half days. We also took two vehicles; I drove my car with the kids (and the cat!) and he drove his truck pulling the U-haul. It was a LONG trip! Two of my kids were still in diapers then, and the oldest was 6, it was a crazy ride. I packed LOTS of crayons, coloring books, cheerios, juice boxes, kid music to play, all of which lasted about five hours! We drove over 12 hours the first two days and then made it here in three hours the third day. 11 hours isn't bad! That's only a day. Just bring lots of snacks, juice and some toys he can play with in the car. Oh...and welcome to Oklahoma!
