None of the above. Booze has killed more people in the outdoors than all the lions and bears combined, by a wide margin. BTW, this represents a distinct shift in my opinion from my earlier days, when I was a member of a hiking trio known as "The Roma Ramblers," the result of our consuming a bottle of Roma Zinfandel on top of our favorite summits. One of our number passed a few years ago, basically from the results of alcoholism. Eventually I got real tired of hauling out the bodies of inebriated climbers and cut way back on the booze.

Rant off, thanks.
