@greenseaman you will have lots of world class equipment to look at and the people who use it are there to talk with as well. Also will be some equipment demonstrations going on so you will want to see what times those are being done on Saturday if there are any particular ones you want to see. Most of the courses are reserved for the weekend/experience tickets I think so you'll want to see what the day ticket allows you to do.
If you can do the Land Rover Experience course then sign up as soon as you come in that morning b/c the list will fill up quickly on Saturday. It's fun. My wife did the course in the Range Rover and then the Discovery. It was towards the end of the day and they wanted to get some film footage so she got to run the course a few times consecutively so they could get different sequences. She lucked out!
There is also a little course you can do with the various BF Goodrich vehicles that you might enjoy. I don't know if it is a sign up or wait in line kind of thing though.
My favorite part is simply seeing old friends, comparing stories from long trips and getting ideas for the next big trip. This summer we hit a primitive spot on BLM land in New Mexico based on a recommendation from a guy I met at Expo 3 years ago and still stay in touch with. Soooo nice to get real input from people you know.
Another thing for me is I've almost always been the only guy there with w Turtleback Trailer and this year there should be ~6 so I'm excited to see others setups. We are trying to decide if we continue with the expo trailer or look towards a 4-wheel camper in the future.
Last year my wife did the winching course, marshalling course and a few others. This summer we were up to our eyeballs in USFS pig paths in Kaibab NF and came across a lodgepole pine in the way that was the size of our 200. I had to back up for well over half a mile with no turnarounds and no room for error. That marshalling course was worth its weight in gold as she did a great job signalling and spotting for me. Reverse with a trailer for 45min with someone who can communicate and not panic is priceless.
