I think that's a cool idea, but more for a regional type meet rather than national meet.
Don't get me wrong, I love making these national meets each year, and I don't mind the distance I have to drive to get to them. But I like being able to do it for only about a 4 day window and not have to do too much driving in between events within that window before the long trip home.
I do agree to the idea to try to spice things up and make things slightly different each year. I don't want to sound like I'm shooting down ideas just because I'm stuck trying to relive the past or anything.
