The "Registration" line to pass security into camping on Friday night of last year was OUT OF CONTROL. Total chaos. Everyone should heed the eminent warning to arrive well before 9pm. If not earlier.
The security is so tight that campers have to walk their gear through checkpoints. This means your gear comes with you in line. Smart kids have wheelbarrows and carts. Smart kids also show up at 5.
I pulled into the parking lot around 9 last year and was in line till 3am...then had the time of my life! The onsite camping is very near perfection.
