I've got the motorcycle camping checklist ( http://www.micapeak.com/checklists/ ) that I've found helpful as I get back into motorcycle touring.

Now I'm wondering - are there items to add to the list that would be specific to the National Rally? In other words, what would you pack for Lima that you wouldn't normally take to a local rally? Here are my additions so far:
1. More money
2. Even more money
3. Camcorder

Speaking of money, is there a preferred type for on-site purchases? I figure cash would be good anywhere, but what about personal checks vs. traveller's checks vs. plastic?
