anyone do any digginig around east-central Illinois?

[bluegrassfan76]

I live in east-central Illinois and as someone who collects soda bottles I would love to go out and do some digging but have absolutely no clue as to where to dig or any good methods to use so I'd love to go with someone who is looking for some help and would be willing to share some knowledge. Normally on Saturday mornings in the spring I'm out crappie fishing but I could put the fishing pole up some time and grab a shovel. Let me know if anyone would happen to live around here by chance and would like to hook up sometime.
