Yellowstone National Park...

Old Faithful Geyser, notice the walkway - click

....Wyoming, Idaho and Montana, almost too big to see,
it would take a week or more, if it were me;
Lamar Valley, Hayden Valley the river falls and all,
and wouldn't it be terrific to see it in the fall.

Buffalo herds and antelope, beavers and raccoons,
and if you wait patiently you could see full moons;
water running swiftly or settled in a pool,
if someone can't enjoy this place, their surely playing fool.
