If you're running barefoot over sharp gravel, then you're just an idiot. And saying you're cheating by using teamspee(a)k is like saying I was cheating for using satellite communications to communicate with superiors in Afghanistan. The insurgents we were hunting could only communicate about a hundred to two hundred feet reliably with the walkie-talkies that dated back to the '70s. We could communicate with an air wing all the way in Bagram, about a hundred or so kilometers north of where we were. I wouldn't say that's cheating.
