I know what you mean, Eric. I, too like to know the era that our stuff came from
and I'm intrigued by the places that aren't listed in our references. Hopefully Allan or Michael will pick up on your post, so the Alibi Room will be listed in the next guide.
I looked in a couple more phone books...it's listed in 1978, but not listed in 1989. (The 10 year gaps between phone books is a killer! )
