People have already mentioned a lot of the stuff I was thinking about posting, so I’ll just second (or third or fourth) a buunch of stuff:
Surprised in a Good Way:
The massive, awe-inspiring splendor of Mount Rainier. I became obsessed with that mountain instantly when I first saw it years ago, and it’s never let up. Ice falls on the glaciers with crevices that would swallow the Sears Tower and you wouldn’t miss it, the size of the Douglas Fir Trees once you enter the park, the “Grove of the Patriarchs,” the pristine meadows, and of course the sheer bulk of the mountain itself.
The Grand Canyon. Yeah, it’s almost like that Douglas Adams description of the factory floor of the planet making company: it’s not really infinity, but it gives a better impression of infinity than infinity itself.
Viewing the North Cascades from an airplane: nothing but icy, sharp, white peaks as far as you can see. The North Cascades National Park features some of the most inaccessible terrain in the U.S. The Olympic Mountains are similar. The tallest of them are “only” around 7000 feet, but they start at sea level, and there are so many peaks your eyes get lost looking at them. The view from Hurrican Ridge is sensational.
Western Nebraska. I expected more of the same (driving east to west): flat, featureless. No sir, it’s corrugated and broken and very interesting. Not spectacular, but very interesting.
Chicago and its lakefront, with the park and musuems. I’m just so impressed that people had enough vision 100 years ago to preserve such prime real estate for the enjoyment of all Chicagoans. It easily have been developed into condos and iindustrial seaport, like Seattle’s waterfront.
Seeing England from the air. Streets in Europe aren’t like in America: they’re not all sqaures and right angles. Somehow this really hit me (“I’m going to Europe”) almost more than anything else.
Amsterdam. I knew about the “Red Light District” but not much else. Wow, is that one cool city! So much to do. I rented a bike for two days and wandered for hours, fascinated the whole time.
Upstate New York. I was unprepared for how beautiful it is, especially the Adirondacks and the Finger Lakes.
So much of the Pacific Coast, from Mexico to Alaska. Stupendous, and a lot of it is still open and undeveloped. Of particular interest: Big Sur, Muir Woods, the Redwoods, pretty much all of the Oregon Coast north of Coos Bay, the portion of the Olympic National Park on the coast in Washington, and so on.
Los Angeles. I expected the horrific urban sprawl and smog, but I was suprised by how many beautiful and interesting places there are as well.
Madison, WI. It has my nomination to be the coolest mid-size city in America.
Surprised in a Bad Way:
The city of Phoenix. Blah. Endless strip malls, cookie-cutter housing developments, and four-lane avenues. Everyone commutes to work in SUVs or pickups (at least, that’s the impression one gets: SUVs and pickups outnumber cars on the freeways but what seems like 10-1). I hate the place.
Niagra Falls. The Falls are tremendous, but the crap plastered up all around them is unbearable.
Seattle’s waterfront. Horrible: hardly anything is preserved in a way comparable to Chicago’s lakefront. There are great scenic spots in Seattle, and lots of them (Alki, Magnuson, Gasworks park, etc.) but the downtown waterfront is not among them.
Cleveland. I don’t know what I was expecting, but it was worse than that. Yeechh.
