I hear the best way to attend is befriend a stripper or any lady entering the contest. This gets you access to the "back stage" area... or on the performer side of the chain link fence
On show day there are too many bozos with cell phone cameras bumping in front of people with proper camera/video equipment in the "general admission" areas of the show. There is also a Saturday "Photo Day", but not all of the girls are available for this.
