We just got home from a 24 day, 3600 mile trip. Traveling thru 16 states, we only added one new national park.... Acadia in Maine. However, we spent 4 days in DC and went to all the National Monuments. We have now been to 40 of our 48 lower states. This was a great trip thru New England.....but no grits anywhere!!
Point Reyes NS, Redwood NP, Crater Lake NP, Death Valley NP, Joshua Tree NP, Muir Woods NM, Sequoia NP, Yosemite NP, Oregon Caves NM, North Cascades NP, Glacier NP, Grand Tetons NP, Yellowstone NP, Haleakala NP.
Of the current 59, I've managed to visit 36 in my first 50 years. I'd have more except I have a habit of going back to my favorites over and over, like my 6th trip to Yellowstone this summer.
Of the remaining on my bucket list, Glacier Bay, Katmai, and Dry Torugas top the list
