Nice, but they're missing plenty, like Voyageurs, Sequoia, and plenty in Utah, to name a few. I'm sorry if the omissions are due to space constraints, but, otherwise, it needs to be updated.
Got all west of the Mississippi without even trying... course, I've been to all west of the Mississippi, so that probably helped :). In the east, I only knew Acadia, Shenandoah and the Everglades.
100% with 2:27 left. as far as adding more I think you would have to make the map bigger as so many parks are close to one another. it would be more challenging than the current one but I understand it might be difficult to create.
The reason I'm late taking this quiz is because we were on a four-week driving trip visiting many of these. Amazing, awesome, wondrous places, all of them. We visited Rocky Mountain, camped in Redwood, then drove to Crater Lake, Olympic, Glacier, and Yellowstone from this list plus went to Great Sand Dunes and sandboarded on the dunes, visited Mt. Rushmore and Crazy Horse, also drove through Grand Tetons and went to several national monuments and historic sites - Golden Spike, Little Big Horn, Lewis & Clark's Ft. Clatsop and Cape Disappointment, Bonneville Salt Flats, Wounded Knee, Headwaters of the Missouri River, got surrounded by a running bison herd on Antelope Island in Great Salt Lake, - the granddaughters were running out of places to put their national park passport stamps. We also went to DeSmet, SD and saw the setting for many of the Laura ingalls Wilder Little House books. Fantastic trip and we met some wonderful people along the way.
Wow, that sounds awesome, ander217! I can attest to the awesomeness of being in the midst of a bison herd. Was surrounded by them on a drive through Custer National Park, near Mt. Rushmore. Spectacular!!!
Once you've done this excellent quiz then if you'd like to cross the Atlantic and test your knowledge of the National Parks of England and Wales then I've created a map quiz at "National Parks of England and Wales (with map)" which you might be interested in trying.
