I have a friend that's in the local Genesis Coupe club and they drive it twice a year and said the same thing. We are going on Tuesday or Wednesday because they said it's less traffic in the middle of the week. I'm not going to try to break and speed records, haha, just want to drive it to see what it's like. Thanks for the heads up though
Actually the run up 129 North from Cleveland to Blairsville is really fun as well. I loved going up there when I had the 2012 Elantra GLS with 6 spd manual. Haven't been up in my GT since I purchased it, but the automatic probably won't be as much fun.
If you ever get out west, Highway 74 (Ortega Highway) in California from Lake Elsinore to San Juan Capistrano is fantastic as well. I haven't taken it in the GT yet but I'm sure it would make it all the more fun.
