I once did the ILS for 25R at LAX at about 3:30am on the way home from Palm Springs. Didn't touch down, though -- just missed and got vectored over the hill to VNY (it was a beautiful VFR night where you could see for miles). Landed at various major airports in the western US.
By far, though, the coolest place I've ever gotten to land at (and I think I got to do it 4 or 5 times that day) was PMD, a/k/a USAF Plant 42. Flew up there in a PA28 for Antelope Valley Career Day in 1997 and volunteered to fly 3 kids at a time around the pattern. Nothing like being at the intersection and hearing "2116Z, hold short of 7 for departing Stealth bomber."
One day I really want a chance to land at EDW but I suspect that, post 9/11, that opportunity will never arise.
