Sunday Randomness #239: A New Sidewalk in part acts Part 1

(This post is in part loosely related to the previous posts on the McDonalds Rebuild from 2012.  Here's the link to part 1 of the McDonalds blog entries which has 12 posts if you want to follow them through to the end:    http://cookingandorscience.blogspot.com/2012/07/sunday-randomness-19-mcdonalds-rebuild.html )  

Part One:  A simple start and the finished product

 First, they mark off an area with little yellow flags and yellow paint.

 They also remove vegetation to help see the markings.

 Then, voilà!  There's magically a sidewalk where there wasn't one before!

Actually, there's a lot more to it than that.  Look for upcoming posts that will cover some of that tedious in-between stuff connecting the yellow markings to the finished cement sidewalk.
