There are sooo many good things to do while at Paducah.
Get the map and schedule. See if there are any classes [if any are still open] that you might take. there are lots of demos and, of course, Eleanor Burns is there. There are usually evening events also. Take time to browse the schedule and map as much as you can.
In my group we didn't all want the same thing so we split up groups so that no person was alone. With cell phones it is easy to arrange getting together for lunch or whatever.
Enjoy.
I wore out socks when I went. So wear good walking shoes [which I did] and have extra socks. It is nice if you don't mind using a fanny pack so you have your hands free. Take a camera or be prepared to load up you cell phone.
