For cities that are looking at redeveloping their downtown, it seems that a Riverwalk is a popular approach.  Pueblo is one of the places that has gone with this approach.  I checked it out when getting dinner one evening.  There was a brewpub along the river and, after some food and beer, I took a walk along the river.  This was an old path of the river but it has obviously been tweaked a bit.  There do seem to be some businesses springing up along the river and there were certainly plenty of people out despite the heat and humidity.  A lot of them were obviously hunting Pokemon.  I wonder whether this will be the center of more development next time I go back.
