What a difference a week makes.... 
Happen to check the weather for Denver at 7AM this morning...18 degrees with snow and sleet. 
Glad RMAF was last week..... 
I am a CA native but I lived in Colorado for 3 years from 2006 to 2009. I attended RMAF 2006 through 2008, but I unfortunately missed it this year.
The weather in CO can change in a hurry. They say if you do not like the weather wait 5 minutes. There were honestly some days where it would be in the 20's and snow in the morning and then be 70 by 6 PM and no sign of the snow from the morning.
I guess the weather will impact the MLB playoffs.
