The probably actually last day of summer

If the forecasts are correct then summer ends today. So, we took the morning off and did an MTB trail near Boulder, called Dirty Bismark.  

It was a lovely ride and we finished it off by riding to the nearest pretentious cafe to NCAR where we enjoyed coffee and pastries. The only problem was that then we had to ride up the hill to NCAR, in the hot sun after already having done 2:30h of bone shaking cycling.
