Visiting Denver

I am traveling to beautiful Denver for work and it will be during the Solatice event. I will have time for walking during my trip. Can anyone suggest a good place I can walk in a loop to fill my bag as I hunt? I have been burning through balls quickly during the event (as have we all no doubt ). I have lures and am happy to lure up the area as I walk so local PoGo players can benefit from the brief presence of this Jersey girl
