NASA's Great Lakes Region is hosting a combined event at Gingerman, so you'll have multiple run groups on track throughout the day. If you're running HPDE or time trial, this is a solid chance to get laps at a well-maintained road course without traveling far. The variety of groups means less downtime between sessions.
