The Rose Festival has selected Governors Barbara Roberts and Kate Brown as Grand Marshals of the 2015 Spirit Mountain Casino Grand Floral Parade on Saturday, June 6. The Rose Festival salutes the leadership and statesmanship of these two historic women. For more than 100 years, the Grand Floral Parade has been a part of the Portland Rose Festival. The only major parade in the country to pass through a building, Veterans Memorial Coliseum that offers spectacular close up views of the award winning floats, equestrian units and marching bands, as they begin the 4.2 mile route through downtown Portland.
