My image for today goes back to the trip to South Dakota this past summer which right now seems forever ago. I took this on the Mickelson Trail during the 20 mile bike ride. I chose this particular section of the trail because it had the waterfall and tunnels as I thought it would be interesting to see. To take this shot I did a bit of a long exposure using a neutral density filter to darken things up since it was a bright day. I was using the hubster's bike seat as a tripod as my bike doesn't have a kickstand. I thought it turned out pretty well with the challenges taking it.
