After doing a bit of poking around spurred on by Gene's "7 X's over Texas post:

I wondered if the information I had about the Blanco Rd address was correct. Well it is and I have come across many old newspaper reports proving it's location, owners and different liquor and gambling problems. So my new headache is to determine what the heck was at the 222 1/2 Travis address. Until then, here's what's left of the Shadowland Entrance. I'll try and post old ads and reports later.

By the way, I've also come across a few other clubs not known to collectors yet but that will have to wait until my research is complete.
