Looks like a fantastic gig!
I know a lot of people rave about the crocs but I can't say enough about columbia hikers. They rule for long days, though they are heavier and your legs are dragging if you aren't used to them.
Did you carve for people? Saw the cutting board. I have a nice one when people are watching but I usually use a plastic cutting board set on an one edge of a cookie tray to catch the juices and bits.
I'm glad you posted this, I have a gig around this size in about a month and I've been debating on how much to prepare.
