My parents live in Litchfield Park, an exurb of Phoenix. Their house is the highest in the neighborhood, and Phoenix is very flat apart from the occasional mountain sticking out. So from the master bedroom's balcony, you can see five different fireworks shows on any Fourth of July. It's also near Luke AFB so they get to see air shows there too. Also, when that power substation caught fire a few years ago, we got a good look at the smoke plume from that, too.
That's pretty cool. You should get a webcam and try making some time lapse movies or something!
