This year they did change the schedule around, I dont like it myself.
It start on a Wed. this year instead of Sat. so the majority of the people will probobly be there towards Fri, Sat, Sun.
Whats more, they started a little early also, daylight savings isnt till Sun the 6th. People with no electrical systems just lost an hour of flying that they have enjoyed for the last several years, i havnt figured that one out yet.
I go every year, and try to fly in for the most part. If you do fly in and camp, my suggestion is to camp out in the "general aviation parking", not the "general aviation camping". The designated camping area is very sandy and dirty, by the second or third day, you got dirt all over the tent and your camping gear. If you camp out at the parking area, its clean and grassy, generally the GA parking is over at the VOR, if you can make it over to that area, you will really have a good spot to camp, and watch the airshow, no crowds, just delightful airplane noise. Make sure you put the GA parking sign in your windshield, not the camping sign if you want to camp at the parking area.
ANd like crash proof said, bring the SPF 10,000, after the first year you learn quickly.
I'll see ya there, have fun.
