I understand your feeling. I haven’t been there either, and have little interest.
When I was growing up, my Dad especially wanted to see every bit of our country. So every summer we got in the family station wagon and tent camped around the country, to nearly every National Park. We saw so many beautiful places. We even went through parts of Canada in order to see Alaska (I’m a native of Florida). The only state I hadn’t been to by the time I was ten was Hawaii, and I dare say only because we couldn’t drive there.
What an education of the vast and beautiful country we live in. One of my favorite places was the Tetons, but all of it truly is America the Beautiful.
Before my husband passed, our plan was to re-visit the great National Parks in the West - we hadn’t been in years - and also to visit the Florida Keys in three sections - we’d already done the top section and were planning to visit the middle section next, then the bottom section the following year but it didn’t happen (husband had a lot of family in the Miami area).
No one else in my family is interested in seeing the U.S. - they are focused on going to Europe for some reason.
