Our closest town is Prineville, OR. Population 12k, I think. One of the nearby ranches rented out to a festival, where they are expecting 40,000 people to camp out on just that one property. Campers are renting tents for $1,500-$2k+ for the week. It's going to be a complete shitshow in town.
The festival is advertising environmentally friendly shuttles from PDX - which is 150 miles away or so. Think about that. A bus holds what - 50 people? It can make how many 300 mile round trips in a day - 3? To move 10k people in and out will require a fleet of 70 buses going in and out of this little town for 24 hours straight. Add to that the cars for people driving, and the logistics for moving about 200 music bands in and out. And that's just for one venue. Other ranches are renting out for different events, too . .plus everyone else who are just planning on driving in and camping wherever.
It's going to be interesting, for sure.
