If you're ever in Phoenix, AZ, then pop by the David Wright house. I only saw it from the outside, shortly after it was saved from being demolished, but have every intention of going back and getting inside another time.

Grand Canyon National Park
I'm embarrassed to say I can relate to this. When I first went to the Grand Canyon at the tender age of 14, I wasn't impressed. I can't believe it now, but it just didn't really do much for me. Fast forward 18 years (oh Christ...), and I can't get enough of that big ol' hole.

Saw this film clip on reddit the other day. Shows M117 bombs falling from a B-52's bomb bay. Very cool to see it from this angle.
Last year I got up close and personal with a Boeing B-29 Superfortress, which is smaller than the B-52, but still has absolutely gigantic bomb bays. Impressive stuff.
Not many of these left

View from directly under the bomb bay. Spacious!
