I have a "X Marks the Scot" badge to donate.

As he is from Fort Worth, I would suggest a venue of a location in Fort Worth. I can do some inquiring tomorrow and Wednesday of the places I reside.

The Flying Saucer in Fort Worth does not have a large bathroom, so I would say this is out.
The Ginger Man on Camp Bowie has a bigger bathroom, but it is not that great in size.
Sherlock's Barjer Street Pub off Camp Bowies is as a larger bathroom.
I will visit a few other places and report back, KK??
