While we are talking about these folks, did anyone hear what happened on San Diego on Saturday? The Emcee sails in in a boat! A BOAT! A real like 18 foot sailboat with blue banner sails! Right in front of the field! And the judges come in wearing all this beach gear, and throwing gigantic beach balls into the crowd, and like 50 people storm the field throwing rings everywhere, and it was just insane.

Detroit:

That would take some serious getting used to.
I’ll more than likely be there, I can’t wait.
Really?
Did you just decide to switch it up?
I think Steve’s MC’d Detroit every year - certainly since 2005. I forget who was announcer in the past, but it wasn’t always Dave.

Simply amazing.
The first year at Detroit I was the announcer and Paul C was the MC. Since then I have been the MC and Dave has been the announcer. I was suppose to be the announcer but Dave asked to switch. I agreed but was really intimidated that year. It has now been 3 years that Dave and I have worked together and he has helped me out lots. I always offer him the MC job but I think that he likes announcing for a change.
