This looks like a really cool show. I don't know if they have these around where I live, but we do have a local auto show at one of local universities. They bring in all the newest models of cars from the big vendors. I used to love walking through the vendor booth area and getting all the free keychains and other stuff that they would hand out. Those lights do seem very expensive. LED's were supposed to drive down the cost of things, not make them go higher!
They do three shows a year here, two caravan and camping and one 4x4 and boating. The two former attract somewhere around 20,000 people each day (5 day shows) and the 4x4 one is a bit less, around 10,000 per day for the 3 day show. A lot of money gets spent. It's good to go around and chat with people, see the new stuff and catch up with some industry people I know. Sometimes I even buy something.
That's cool. I've been to a camper show before, but never a 4x4 show. I'd still like to make it to one of the US's famous gun and knife shows at one point in my life...
They're a lot of fun and sometimes dangerous to the wallet. 😉
