San Diego or Colorado

AFAIK ski/snow season won't be until early December at the earliest for Colorado. With that in mind, I'd pick San Diego just for the weather alone.

 

Colorado, where the beer flows like wine.

 

SD. too early for snow activities in CO.. it'll just be cold

 

Seriously, it's TOO DAMN EARLY to ski in November. Unless he enjoys really cold hiking, the obvious answer here is San Diego.

 

You can hike or whitewater raft

 

Whitewater rafting in frigidly cold water is a miserable experience.
