During the summer, the downtown streets are closed in Klamath Falls for Third Thursday http://www.exploreklamath.com/?p=16.
Street vendors, wine tastings, music, pony rides and families cover the entire area. I was assured not everyone who lived in Klamath Falls was there, but I doubted it. We could not walk a quarter of a block without someone in our group running into a good friend, neighbor or relative.
I was also assured not every family in Klamath owned a dog, but check out the dog bar below. All dogs are welcome at Third Thursday.
