Hello, I am heading to Branson MO in future, been going there over 20 years know how to get there. I live in OKC, OK when I pulled my TT there a few times I been I-44 to Springfield MO,HWY 75 tryin...
I have not taken HWY 412 but have driven HWY 62 many times. Either way you will end up on the southern part of 65. That part does not have the 3 hills you are talking about.
If you have never stopped in Eureka Springs this would be a good time. Its worth a day or two.
