Huntz: I have never seen Mr. James Arness in person but had occasion to meet and talk with Mr. Clint Walker at the Portland, Oregon gunshow some years ago.
He dwarfed me - not just in height (I am 6' 3" tall) but his chest was at least 5" wider than mine and it was at least 5" deeper than mine!
The giant and gentle man was indeed huge - and he seemed to be enjoying himself at that gunshow.
I am certain neither gentleman would be interested in or stoop to the level of engaging each other in a fist fight if that was what you are alluding to.
I admired them both for their acting skills and gentlemanly conduct while in the public eye, most all their lives.
Hold into the wind
