See this - http://www.ncbi.nlm.nih.gov/pubmed/15919576 - for good advice. The information doesn't seem to have changed much over the years. I was taught the crouch position - keep your boots on, squat down, lower your head, and keep your mouth open (alleviates ear damage, I believe). Scatter the group so that one strike doesn't take out every one.

I have assumed the position twice, both times in a tent at night, acutely aware that the tent poles did not constitute a Faraday cage. The second time I was taking my darling bride up my favorite mountain. A thunderstorm rolled in and I said, "It's time to assume the position," drawing a puzzled look from my sweetie - she was not sure of the context of my statement. That was twenty-five years ago this November...

Has it struck anyone else that this thread has ignited something of a flame war?
