Hey, I just got home from a ride up into the Adirondacks to pick my son up from camp. (Getting dropped off and picked up at camp on a motorcycle has been deemed just about the coolest possible camp experience by staff and campers alike!
)
I have a spare J-box you could borrow to bring along with you to the National if you've got time to meet up tomorrow. (Sunday) I have no plans, and it would be cheap insurance. Just return it after the National. It's only got 58.8 miles on it, so should be in good shape.
I'll PM a copy of this message to you along with my number.
