Can we bring in campers on Wed Aug 1st?

Yes. The Glen's website indicates that for this event, camping opens at 6.am on the wednesday.

I believe so. But check online at their web site. They have all the do's and don'ts on the fan guide section

If you can try to park your camper near the bus stop section. One of the best parts of the track to watch

See Mike's and Terrence's answers.

I don't camp when I'm there
