Watch as much of the feeds from Bristol you can this weekend, even if you don't much care for NASCAR. You will see many high shots that show all the camping and surrounding of the track. And what you see is maybe only 60%-70% of the quantity of people and campers that will be here in 3 weeks. Most of what you see from the high shots are campers and not just cars. LOTS of camping. Carnival rides. Food and souvenir vendors. It's quite an even for 2 or 3 days.
