I missed the Iris Festival this year. I've missed it for the past several years. I did manage to capture these outside my office building though.
Every year the local iris grower opens up their display garden to the public. You can just wander around and view the many varieties, and you can purchase if you like. In past years I've spent time taking many photos, but I just haven't managed to get out there in recent years, and now it's gone until next year.
Oh, and the town does have an Iris Festival with a parade and carnival and such.
