It is an ampitheater with reserved seating on what would normally be referred to as 'main floor' but these seats are connected and not moveable like most main floor seating setups. I enjoyed the acts but I also liked the venue. This is the second time I have attended a concert there (Train/Gin Blossoms in 2014). My wife and I made the two hour trip from metro Detroit area so that I could attend the Def Leppard/Tesla concert at the outdoor venue (they have a smaller indoor facility for some events) while my wife did some gambling in the casino.
