Thats great that you found someone to handle all those bottles for you. I was hoping you would. Hope you get alot for them. Sounds like you hit the mother load for bottles.

It does interest me but have no experience at it. I do have two locations that have been undetected, they both have lots of bottles laying around. Most are broken I presume because they get water in them and freeze.
