Captain, Idaho is a lovely state. We did the same trip in 2016 and 2017- went through the National Glazier Park in Montana from east to west, then turned onto LoLo pass, 99 miles of curvy road, like you said "those swippers just keep on coming". My Arvita is a pic taken near the Glazier Park.
Btw, I enjoyed all your videos on utube.
