Treasured Places (aka, every national park unit, national monument, and national conservation area in the US—likely still the only person to have visited all 484 of them)
World’s Largest Balls of Twine (four of ‘em!)
WWII Japanese Internment Camps (in US)
All the craft breweries in the US territories (and DC)
Some examples of quest I’m still working on:
Highest Points of Otherwise Flat States
Major sites of the Manhattan Project
Crossing each of the 107 borders between two US states
Every area that was once a National Park unit in the US
Visiting one site (birthplace, home, gravesite, etc) for each US President
50 countries before I’m 50
Each of Phoenix’s “Points of Pride”
Scenic driving the 26 major paved passes over the Sierra Nevada Mountains
Here’s a more complete accounting, though it’s missing about 5-6 new quests I adopted last year 🫠
