Dear CO Native
I feel your pain, as Slick Willy used to say.
We flew in and out of Denver, picking up a car for a family wedding in Laramie and some tourism in both Dakotas. We over-nighted in Fort Collins on the way to Laramie and Loveland on the way home.
It had been close to ten years since we made a similar trip to Laramie and Fort Collins; we had family in both places at the time. I can hardly believe how much worse traffic has become, or how the I-25 corridor from Denver to Cheyenne is looking like the I-95 mess from Baltimore to Boston because of rampant development. I remember when Ft. Collins was a nice , livable college town - it ain't no more.
Every road we used in the area was bumper to bumper from morning to night; I25, I70 and their "2" feeder roads. Even 85 and 285 were packed at times and in certain places. The highway to Colorado Springs looked almost as bad from the glimpses we had of it.
Our relatives lay the blame the same place you do - GD Californians!
