Arrived in Quang Tri Province in November of 1966 with just 2600 of my closest friends. 13 months later, after monsoon, mud, heat, dust, and insects of the most diabolical descriptions, it wasn't the conditions that held my attention and occupy my memory. Since then I have competed in wind, rain, snow, and sweat running in your eyes heat, still enjoying all of it. I've sat up in the wind in a deer stand in 15 degrees and sub-zero wind chill from pre-dawn to post-sunset. Still going back.
Even a bad day with a rifle in one's hand beats all but just a handful of other things on the planet on a proverbial 'nice day'.
