Sevierville and Pigeon Forge basically just run together and Gatlinburg is five miles further. I drove thru all three this morning. Gatlinburg is very picturesque and very compact. It is very walkable. Parking is an issue in Gatlinburg and expensive. Traffic was congested today. I can only imagine what it is like in peak times.
Pigeon Forge and Sevierville are more like Branson. You either take the trolley or drive.
I left Pigeon Forge about 12:30pm today. I drove 365 miles to Paducah, KY. I ran into traffic congestion in Nashville today and again just 20 miles from Paducah. Arrived at Duck Creek RV Park, Paducah, KY about 7:30pm. It is central time zone here so it is actually 6:30pm.
I am 412 miles from home. I hope to sleep in my real house tomorrow night.
