Greetings! My 21 year old son and I will be taking a road trip from the LA area to the Wash DC area in July 2018. We will take approx. 10 days (one-way) for the trip. The first two days will be a lot of driving, with the intent to make it to Oklahoma City by the 2nd night. We are anticipating 10 hour driving days the 1st two days, as we want to get to OKC quickly to visit relatives. We will be in OKC for two nights before heading off towards TN. Our plan is to stay one night in Memphis and one night in Nashville. From Nashville we'd like to take 3 - 4 days to drive up to DC. We'd like to see the Great Smokey Mountains and part of the Blue Ridge Parkway. We love to take pictures and go on short hikes. Any advice as where to stop over during the 3 - 4 nights from Nashville to DC? Thanks for any advice you can provide!!
