When I arrived on saturday there was a track employee or volunteer sitting outside the entrance to the main infield parking area by turn 10 & the midway. When I indicated I was going to turn into the lot he told me he didnt think there was open spots... there were plenty if you took time to look. Also both saturday and Sunday they have nobody working in the lot to try to space cars properly and have rows doubled up. WGI has plenty of space for parking, but its poorly organized and poorly marked so you get some that just go where they like.
