Exceedingly off-topic diversion.... LOL!
I was camping in the forest behind our home over the weekend, and around mid-day, my wife and I noticed a very large insect flying noisily and somewhat clumsily around the site. It landed on a spruce tree. HUGE wasp, about 1.25" long, with translucent black! wings and a huge (3/8" long, 1/32 diameter) stinger. Seemed absolutely oblivious to us, paid us no mind. We noted a half-dozen more over the next few hours.
A bit of googling when home revealed them to be Great Black Wasp, Sphex Pensylvanicus. Harmless unless really annoyed, and somewhat similar to the cicada killers.http://bugguide.net/node/view/5530
