John, welcome to the forums, the Reno bottle show is July 17 and 18 at the grand sierra resort, 2500 second st in Reno free admission sat 9 am -4pm. I would bet you could hook up with some diggers there........Andy
I'm the Winnemucca bottle collector that Leon mentioned. I'm hoping to try and get permission to do some digging in Dayton. If I do, I'll get a hold of you. ~Mike
