If I may comment here about this, I know this channel is about national parks proper, but I really do think people put way too much emphasis on national parks when there are so many great places to go in the national parks system that aren't national parks. May I suggest a video of some of the places you really enjoy that aren't full on national parks? Maybe it's a historical park or it's a memorial or a national monument or a national historic site. There are lots of great places to see. I implore people to not just limit yourself to just national parks.
Great idea - and I've done some of that. Here is a playlist of National Park Service Locations (meaning locations taht are managed by NPS but not the big National Parks. Check it out. ru-vid.com/group/PLzMWhC-SYlDzS9ZnB5UoLIRO8MsVe8RQG
