Are you in the Boulder/Loveland area? I thought I saw all of Loveland was to be evacuated. Flash flooding is scary because it does come on so quickly. I'm glad that you are safe so far.
I remember about 20 years ago my mother and I had to go downtown, which is at a lower level. We had all this rain and by the time I was ready to go back home, I couldn't get through any of the streets to get home. I had to go waaay out past town about six miles to circle around so I could get home.
