Main Events
Live Entertainment

Entertainment activities include live music from a range of local talents on the main stage downtown. The beer garden is open to serve ice cold refreshments.

For as many years as we can remember, Sage has filled the downtown and has become an annual pilgrimage for class reunions or those that just need to come back and get that home town fix.  This year is no exception with Mark, Randy, Barry, and Jerry on the main stage rain or shine!
