Denver Colorado Cherry Creek Park Push Button colorchallenge mondayred

I found a button when I was walking down in Cherry Creek Park in Denver, Colorado. What do you think will happen if you push it?

I did push it, but it was getting cold and soon to be dark. Nothing happened and no one came before I climbed back up into the city.

This button is right around this underpass, in case you are in Denver and want to try it yourself.

My post today is for the #colorchallenge #mondayred by @kalemandra.
