We also went to Idaho as a kid and I remembered it as fun and full of adventure. Part of that was due to staying at my Mom's cousins farm. He grew potatos, alfalfa, as well as other crops...mostly potatos. So we got to drive farm equipment and help out with chores around the farm. In addition, there was camping,hunting and fishing plus some sight seeing.
As an adult and married we went back up to Idaho on our way to oregon and Washington. We went to Craters of the Moon, Sawtooth and a few other areas. My adult impression of Idaho is unless you like to fish or hunt, there's not much to see that is different than the deserts, farmland and mountains of other states.
We are not in to hiking, fishing or hunting... we do like to visit old towns, museums, unique shops. Idaho has all of this.
I did enjoy stopping along the roadside and picking fresh wild aspargus. It was abundant in the Gooding area and very flavorful. There is a bridge spanning a gorge near Twin Falls that we walked across, the view down into the gorge is great. Also Thousand Springs is impressive.
