Some camping questions

[mazdaP5]

Good Morning Jeff!
Your airshow passes are separate from your camping. You can buy either daily or weekly airshow passes.
If you are camping, you would only need parking if you intend on driving from camp and parking, but that wouldn't get you any closer.
Have a blast, it's hard to screw Oshkosh up.

I'll ad to mazda's post that they will happily sell you the wristbands along at the camper registration (as well as an EAA membership if you don't already have one).
