For the guys/clubs who put on shows.....pre-reg?

I was just wondering if most of you guys do pre-reg for your shows...or do you find it to be unnecessary? I guess the biggest benefit is not having to carry around a bundle of money on the day of the show....let meknow your thoughts......

 

I organize a couple of car shows a year and offer (but don't require) pre-registration for them. It really makes the check-in process go much smoother if you don't have to collect money and information at the gate for every car that comes through.
