Well, I haven't spent any time on a horse, nor have I spent much time carrying a six gun. As such, I will not comment on either.
On the other hand, I have spent considerable time outside camping, hunting, working etc. and most times it is not nearly as glorious as the pictures and romantics opine it to be.
Living outdoors and cowboying had to be one rough way to make a living.
Some folks would have a hard time living out of a cold drafty bunkhouse !
