What was Bob doing?

While Lukas, Noah and Christina enjoyed themselves in Europe, Bob stayed behind to continue his work on his dissertation, walk our dog and in his 'spare' time create a beautiful patio for us to enjoy in the cool evenings that Monterey offers almost year around.
A year ago, this spot had an unsightly metal shed on it, today it is a wonderful spot for family gatherings around the fire pit. Do not let the finished product deceive you, it sure looks simple - it was anything but. Sifting out the lava rocks, digging down half a foot plus, flattening the ground out, rocks, sand, bricks, more stamping, more sand, more stamping and more sand. And if that was not enough, the area for the patio was not a square, so Bob also had to cut bricks! I have a whole new appreciation for anyone who has a brick patio now that I know how much work is required.

Clearly, one has to wonder if there is anything Bob does not know how to do?? I am sure this was not part of required course work for his PhD, nor any of his many other degrees and certificates.. He is truly amazing!
