... five years pass ...
... almost five years ...
Most of those visits were to the northern part of the front range cities. I did go to Colorado Springs once, Estes Park once, a few drives through Rocky Mountain National Park and I-70 and Grand Junction, but Denver/Boulder/Fort Collins were my most frequented places. In fact, I don't think I missed Boulder on any one of those trips.
Eight visits in five and a half years was enough to become familiar with the area and develop friendships and have favorite venues and restaurants and more. Then a five year gap. So much changed! Socially, and in the city, and people's lives.
