I was looking forward to a nice episode of "Conquest" after "Mail Call" went off.  But even when this thing came on I thought, "well, this might be good... I might learn something." Now, I just wish I'd gone to bed early.
You could definitely peruse this site for a half hour and get more/better info than what that program had to offer.  I even thought about sending a letter to the History Channel about it, but then I figured some of their audience may have actually needed that information.  Not everybody comes here and discusses survival all day like us!  <img src="images/graemlins/smirk.gif" alt="" />
