My dad signed up for this and showed up before the official 4am leave time and group had already left without him. I had originally planned to do this as well but still recovering from motorcycle accident last November so didn’t think I could make 1000miles but planned to do it in future if they continued. But based on my dads experience this time doubtful I’ll give it a go. He’s now out not only the registration fee but also booked a hotel nearby to be able to crash afterwards and be around for the party the next day. Hotel was non refundable at 4am the day of the reservation.
