I suppose Albert Hammond could have used one.
I think it's where the Hollies met.
Rihanna has one, one, one.
UPDATE: original cache was an old patio umbrella that I found out here while walking the dog. Unfortunately the umbrella has finally succumbed to the weather and is just about completely gone. So I replaced the container and moved it a few feet in a bush. Please replace it back this way, facing down. Thank you!
