I presented a couple talks at the a conference held at Miami University. While it was a working vacation it was the longest, and only time we have both been away from Jack. He didn't mind too much as two of his NY grandparents kept him busy with fun and games (see video below).
At the end of the conference it was time to relax and enjoy the temporary lack of responsibility.
Happy boy and grandparents!
