At our recent RV show a dealer had a ball toss game where you could win $$. Big hole was $10 and smallest hole was $1,000. There was a lineup to try it. If you got close enough the fine print on the board said whatever you win is how much you save off the purchase of a new RV from them. Wow, how cool is that? :R
A few years ago we won a free membership in a CG network after filling out a ticket for a draw at another RV show. Turns out you could only stay a couple of days per year and not on holidays. You've gotta know every ticket was a winner and they're out to snag buyers for a full membership.
