Jay, interesting, since the title mentions Lithia Park, I am assuming this is Ashland, Oregon. Lithia park is still a very popular park. I wonder if that building is still standing? Will have to try to look around next time I'm up there.
Looks like about a '15 Dodge Brothers in the left background, that might help date the photo.
Google is wonderful . . .

They have great water at Lithia Park. It tastes like Alka Seltzer and is quite good for acid reflux. I like to take people who haven't been there before and let them get a drink from the fountain! It's interesting to see the look on their faces.
