The bottom pic is the motorcycle parking area on the backstretch of the oval (that's the back end of my Sportster on the near right). They've got a nice setup for motorcyclists. Enter gate 10 from 30th Street on the north end of the Speedway, and you are quickly in the parking area. They even handout kickstand pads when you pull into your spot. They have secure gear check-in stations nearby, so you don't have to carry your gear, or leave it on the bike.
