Six Blocks From City Hall!

One feature of La Crosse that I really enjoy is the marsh area smack dab in the center of the city, giving residents easy access to nature without having to travel for miles and miles. For example, this scene is located only six blocks from La Crosse's City Hall. I doubt if there is another mid-sized U.S. city (50,000 to 100,000 population) where such a wild scene can be found six blocks from city hall.
If there is, please let me know.
