The Rocky Mountain Arsenal National Wildlife Refuge was an extremely pleasant surprise in such an urban area. Great trails for hiking abound, as do animals. Tread lightly, and don't forget the camera.
Find the bison!
Patterns in a frozen lake.
This guy was down one antler. Still a beautiful creature, though.
And the whole thing was free, which makes it even better. I'm still surprised at how few people were there on a Saturday so close to Denver on a warm-for-winter day. We'll definitely be back, time and time again, and I can't wait to discover the different animals and sights in each season.
