People from Idaho would tell you, "It sucks here! Don't come! You'll hate it."
The reality is that this track takes you through one of the most beautiful parts of the US. Oregon and Idaho have an amazing array of climates and landscapes. You could be wakeboarding along an almost tropical Snake River in Hells Canyon in the morning and then hiking in the high alpine of the Wallowa Range later that day.
Truly my favorite part of the country and I'm glad that it's not overrun with tourists.
