I was born in Idaho Falls and spent a great deal of time there growing up even though I was raised in Utah. But there's a few things about Idaho I really miss.
-Idaho Falls on the 4th of July, there's nothing like it, the whole town seems to just relax and chill, the weather's perfect and the fireworks are excellent.
-Square Ice cream in Swan Valley.
-My family's lodge in the Teton Valley.
-building snow tunnels in the winter (not enough snow as of late)
-wheat fields, I love driving past them in the summer evenings, they smell great

-Island Park
-Idaho Falls Greenbelt
-Fishing the Teton River
-Heise Hot Springs
-And of course the snake river and falls itself
I hope to get back there someday, it's the best!
