Fall @ osmosis: Peaks, Pines and a Raven
Featuring Diane Pike [ D Pike ]

Mark your calendars for a SECOND Friday opening. On September 11, we’re welcoming Diane Pike’s new paintings inspired by a four week camping trip through Banff National Park.

It’s a big night in Niwot Colorado. Why Not Niwot? closes at Niwot Hall the same evening, with awards and live music from the Niwot Semi-Marching Free Grange Band, so plan to make a full evening of it between both venues.

Opening reception 5 to 9 pm. See you there!
