No need to apologize for posting your warning! I'm well aware of the lightning risk, but there's nothing wrong whatsoever in you making sure of it!
Your comment: "'They' say that your body is at its worst in the 2-5 day period after arriving at altitude" is exactly why I'm seeking an answer to my question of "Should I?"

Still, I'm following a couple of other lines of inquiry. If I get useful answers I'll let you know...
