In a couple weeks we will be traveling from Adairsville GA to Huntington beach which is just south of Myrtle beach,Will I have to deal with any big Mtns. on I-20 going east-Thanks Rich
You don't go THRU Florence, you bypass it by continuing on I95 for a few miles and there is a turn off to Myrtle Beach that goes around Florence. You can you through Florence but I do not recommend it.
