Hi Beverly...I live in Las Vegas, and the town you are talking about is Boulder City, NV....this town was created to house the workers on Hoover Dam. It is a wonderful quaint town (no gambling allowed within the city limits) my husband and I would love to live there..but it is too pricey for us. We remember a gift shop in Boulder City in the 1970's.....it was old, everything in this town is old...
Is your great uncle still living? What do you know about him? I would like to help..email me privately with what information you have and I will see what I can find out.
