Minidoka, one of 10 relocation camps the Japanese americans were forced to live in during WWII. It was located in a "no mans land" part of Idaho with very cold winters and extremely hot summers. Minidoka is now a National Park with many plans for a visitor center and continued preservation of the area.
Idaho - I found the original site of Evel Knievel's famed Snake River Canyon jump from back in 1974. Amazing to see it's still intact. Also exploring the Snake River Canyon area and get lucky enough to see some incredible BASE jumpers! This area is a must see in Idaho for sure.
