We do have time limits at Lawrenceburg.

I might be wrong but I thought the only night that ran late was the "Sprints, Sprints & More Sprints Night."
Qualifying the MASS sprints is what started us out behind (we didn't start the heats until 7:49).

The time stamps on the last class of the night from my racing format program:

April 18th - mini sprints - 11:40 pm

April 25th - pure stocks - 10:40 pm (sprints 9:43 PM)

May 2nd - mini sprints - 10:41 pm (sprints 9:48 pm)

May 9th - mini sprints - 12:48 am (MASS sprints 10:05 pm)

May 23rd - TQ's - don't have time - (KISS sprints 9:58 pm)

(The time stamp is when I closed or saved it for the last time. The races could have been done sooner.)
