If I were only watching this year, I'd definitely vote for 4 or 3. But knowing that I'd have to drive essentially through
a sea of people at the very point in the course were I need to see the most (and should have to worry about dodging people the least) means I have trouble really going along with 3, 4, or 5. If people can barely be kept all the way off the course on Hills 1 and 2, where its a straight shot and they can clearly see when a heat is about to start, I seriously doubt the overeager chute-dwellers will manage to stay out of the way completely.
I'm not trying to say there shouldn't be people hanging around in the chute by any means (its where I'd go if I weren't driving), it just seems to me that having the jumbo tron at the apex would encourage people steadily encroaching upon the course more than prevent it. And that's not even taking into account the trees and gazebo on the inside of the course that take up/block valuable viewing areas if the jumbo tron is at 3, 4, or 5.
Anyway, that's my two cents....and apparently I was ninja'd by Sam while I typed all that up...I'm posting anyway though
