Missing animals

I get tips from my fellow students every once in a while about cool places to go for cool pictures. On occasion, when I try out one of these locations, I see some cool animal that isn't seen very often. Most of the time, that doesn't happen. 

This was one of those times. I went to the Wheatridge Greenbelt to try and snag a couple pictures of some red foxes because they're known for letting people feed them chicken bones at this particular location. After my 3rd time of going there, I gave up on the foxes because I needed a picture for my class so I decided to do timed exposures of the river flowing parallel to the walking path. 
A couple of the images turned out really nice in black and white as well as color so I couldn't decide which one I liked more. Let me know which are your favorites.
