### Day 200 - Yep... 200.

200 runs.

Seems like it should feel substantial. Like an accomplishment.

Doesn't.

Feels like a Monday.

That is kind of a good thing. I think. Run 200 was a run, and that's good enough.

So, lacking in interesting insight, and still a little shell shocked that my daughter turned down a chance to go shopping for clothes with her old man picking up the tab, I'm turning to the good folk who contribute to the internet thing that is Wikipedia.

Mostly because I couldn't have come up with anything nuttier related to the number 200:

Good running,
Doug
