Weapons accessories, including magazines, mostly for The Black Rifle. (Thanks, David!)

The drool-worthy Kriss .45-caliber SMG on Discovery's FutureWeapons. If I'm in SWAT or Special Ops, I'm petitioning my commanders to give this thing a serious look once production ramps up.

Wifi access at 219 U.S. airports, listed alphabetically by city (with corresponding airport codes), noting which ones are free, and offering hourly, daily, monthly, and other charges. (Thanks, Eric!)
