I have an answer to my question. There is no security for Sunday night. If enough people want to split the cost. They would be glad to provide the service.
Pretty sure 99% will be leaving back to their home (state) that afternoon. You sir are likely to be the 1%.
We had briefly thought about staying at the track Sunday night and then driving home on Monday, but decided to head home after the trackday and if we need to, pull over, we'll hit an Interstate Rest area and maybe snooze for a few hours in the T.H.
We stayed over after a VIR event one time and got to see this brand new being delivered to the track via a Lexus 18 wheeler....never hurts to ask!
