Take the rain coat. You won't be going that fast that the extra item will matter.
Your bike will get dinged. Mine did last year. They say they have professional handlers but in reality they just dump the bikes on top of each other in a truck. They get all tangled up.
Pay attention. There are many riders who are not experienced and are dangerous. They sway back and forth, stop short, talk to buddies and are not aware.
I am jealous I can't go though.
Will go for the cross country ride in 2006.
