I know this is an insane
goal. I also know it overlaps with the Visit All 50 States
goal.
So what?
Using
this list,
I have visited the following parks (with years, if I remember):
The Badlands, SD, 1993 (first time)
Carlsbad Caverns, NM, 1993
The Everglades, FL (I
think
I have been here...)
Grand Canyon, AZ, 1993
Mammoth Cave, KY, 2004
Petrified Forest, AZ, 2001
Rocky Mountain, CO, 1993
Saguaro, AZ, 2001 (first time)
Wind Cave, SD, mid-90s
I've also been to numerous national historic sites, battlefields, etc.
Of course, the best source of information is the
National
Park Service's homepage.
