Charlie,
Thank you for posting these photographs. I used to live in Glendale, California about 25 years ago. I think I lived about 7 miles from LA civic center. Many of the streets in your photographs look so familiar. I drove a delivery truck for a printing company in the early '70s. I remember the Morrison Hotel and Hard Rock Cafe seen on the front and back of the Doors album Morrison Hotel. I wish I'd carried a camera with me in those days.
Best,
Dave
