Is it wrong to envy a turtle?

When I'm in the office, I have everything pretty well under control, thanks to my computer, calendars, company network, email, etc. But when I'm at a show site, I often have nothing but a loose-leaf binder and a cell phone that doesn't even work half the time because of the show's location.

How can I stay organized -- and in charge -- at show sites? What tools and techniques do other people use?
