During my Fredericksburg concert (see post below) a gentleman came up to me during intermission and asked that question. This time, things turned out differently than they usually do.
He asked me if I was related to a Bill Tullos who lived in Venezuela many years ago...
"Well no, but...are you sure his name was Bill?"
"Was it Ed?"
"What did he do in Venezuela?"
"We worked for an oil company together."
"OMG!!!! My grandfather, Ed Tullos lived in Venezuela and worked for an oil company!"
Apparently, this gentleman worked with my grandfather way back when. He said he was a nice man. Unfortunately, I didn't get a chance to speak with him for very long. But, I did get a picture.
