I think in every state in the US people say "if you don't like the weather, just wait ten minutes it will change" or "typical "insert name of state here" 70's one day 20's the next". I think it's pretty much how every place in the United States is. I've lived and visited quite a few in my years and I promise everyone says that.
I grew up in Ecuador, on the equator and the weather was literally the exact same every day. During rainy season= sunny then storms in afternoon evening. During Dry season - sunny. Literally same thing every day! Perfect 70's during the day - and 50's at night. How can you complain? (but that was at 10,000 ft in altitude, down on the coast or jungle is another story)
All that to say - Literally Sunday afternoon Richard played golf and then Monday night we got a few inches of snow and Tuesday we were playing in the cold, white, fluff stuff.
But I refuse to say one of those cliche sayings about Colorado's weather. :)
