being a 4x4 101 event, we expect (and hope) you will learn that having the trail gear reqs will help out on the trip. Being a beginner, at the very minimum i would suggest having or at least deciding on what your front and rear tow points are incase you need a little tug. WP is very stocker friendly, but depending on conditions can get sticky quick!
as for the meeting place, well basically what you said, but dont forget, were not just a jeep club :)
I dont believe i have ever changed a tire at WP for a club event, though having a full size spare becomes more of an issue with a locked vehicle. maybe someone else can chime in a this.
hope to see you!
