Steve,
Congrats on a successful, big, demonstration. They are important, although it might take a long time to pay off. I have been contacted by people who saw a demo, or drove by a mobile milling appointment, years before. With kids you have to front load your presentation, attention spans are short but, if you get their attention, they'll remember it a long time. One day, one of those kids, parents, or teachers will see a tree blown down in a storm, or being removed by a tree service, and think, "you know, there's this guy..."
I do a couple of them each year, including one next month for the International Sculpture Conference. I'll be milling urban logs on the campus at KU, along with a metal casting demonstration, and a stone carver.
