Newbie to nationals questions

["Glen E. Thompson" <glen.thompson@cox.net>]

This is my first trip to nationals and I had a few questions I couldn't
find answers to.  

1. I will be traveling in my motorhome.  I understand there's an area
for parking it.  Is water available to fill my tanks or do I need to
fill before getting there?

2. Getting around the event site - how far from RV parking to paddock
area?

3. Expected day of event schedules - how long are the heats?  How much
time will one be working the course?

4. Any other tips for the newbie?

thanks,
glen
