oh cool no classes.. hopefully you can get in and out. definatley sounds like its more about the adventure.. sounds liek there will be a lot more stops along the way which is cool... also sounds like ont he "drive" days they will stop like half way or so for the night. i'll bet it sold out in a matter of minutes.
I may have spoke too soon. Looks like we might still be stuck with the A,B,C,D groupings like some of the other events despite not having classes for this event. Found this while reviewing the Sick 66 rules:
It won't surprise me if this ends up being a thing since the event sold out. I know they didn't do this at Death Week, but that event only had like ~100 cars, so they didn't need to. They probably will here since it seems like Sick 66 will have a much larger car count. I guess we'll have to see.
