Given the weather, and the aircraft, i thought it best to take this shot and upload it for all to see. N869HH, in the photo, was one of the few Janet Airlines 737-600s I haven't captured yet.

Living in Vegas, you get to see these planes numerous times from Monday thru Friday, so they're pretty common (considering there's a Janet Airlines hub in McCarran International). However, if you do not live in the city that never sleeps, than this U.S.-registered 737-600 and five others are very difficult to catch.
