Roller-Coaster Hills, North Dakota-South Dakota Border Area.
"The road south is awful. Choppy, narrow, bumpy concrete with a bad head wind, going into the sun and big semis going the other way. These roller-coaster hills speed them up on the down side and slow them up on the up side and prevent our seeing very far ahead, making passing nerve-wracking. The first one gave me a scare because I wasn’t ready for it. Now I hold tight and brace for them. No danger. Just a shock wave that hits you. It is hotter and dryer. .. At Herreid John disappears for a drink while Sylvia and Chris and I find some shade in a park and try to rest. It isn’t restful.“
Herreid, SD. We have crossed ND-SD border just before arriving here. Note roller- coaster hills and bus that can cause “shock wave” blast.
