Random Old Bozeman Thing I Found, And Random Thoughts It Generated

This is what I found while I was walking around getting some fresh air today.   I thought it was weird that I found it 101 years after it was stamped and almost to the day it was stamped.  I think part of the reason I found it so odd is that it's not marked as a historical site or anything special. It's just a stamp in the concrete marking what day it was poured.  I would have never known how old that concrete was unless they had marked it. And for whatever reason it made me tailspin into thought about who had stamped it? Did they have a family?  Does that family still live in Bozeman?  Does the family even know that part of their family heritage is stamped into a random sidewalk?  Why don't we do this more? And then I looked up and was confronted with why we don't do thoughtful things like this anymore.   For the same reason we drive things like this.....

Haha! Ok so that last part I made up just to poke fun at KISS' digital warrior, Cole.  This is his car and he gets an amazing amount of crap for driving a Cube.  But for some reason he is always the one we want to drive to lunch?

Question? Can anyone guess what street the stamped piece of concrete is on in Bozeman? Or are there anymore of these that you have seen?
