I have been to Oshkosh before but just for the day. I would like to arrive on Friday 3 days before it officially starts and camp in camp Scholler in a camper. I’m not really sure how it works getting there before it starts. If I want to go to the north 40 or homebuilt or warbird area do I have to walk there or are the free trams running? Do you have wristbands if your camping? How about the official show grounds are you u able to walk around while they are setting up airplanes and in any of the buildings or is that area only open on Monday when air venture officially starts? Any info on things to do before Monday morning such as food vendors or daytime and evening activities on the grounds would be appreciated . Thanks!!!
