I still get asked y I like to dig for bottles, well it's to find a new kind of bottle of cores but there's another reason. going back in time! It's not just finding bottles it's the journey.When I open up a layer of old trash that hasn't seen the light of day for 80 or a 100 years I am now back in that time , the people there lives the world they lived in now revels it's self to me , and time then becomes truly relative . The questions about the past can only be answered by research and observation . Happy digging !
