An extended Riverwalk would be great. We could walk, bike, jog for miles without dealing with cars and enjoy the beauty of the river and city. If private property owners block the Riverwalk on their property, why can't the city build the walk 50 or 100 feet off the shore but parallel to it, like a long boardwalk -- similar to the elevated walkway at the zoo-- but over water. That could be cool for short distances to circumvent difficult property owners.
