Cherry Creek State Park and Lake is a 5,000 acre refuge right in the middle of south metro Denver. It is 6.5 miles - partly by trail (soon to be finished) from my front door. The trip around the lake is about 9-10 miles, and add in about 4 miles for the spur trail, and the total ride was about 28 miles.
There are deer - I watched one for some time, but did not get a picture. Lots and lots of bicyclists from the nearby neighborhoods, and commuters using the trails as a short cut through town. There is a major southern downtown area just to the west.
Total smiles per mile - an average of about 10, for 280 smiles. Or thereabouts!!
Here are some pictures from this morning's ride. (I have been riding about 125 miles per week - that's a LOT of smiles).
You can see the business areas around the park.
First is my morning breakfast break.
