I have a few friends that all they do is run the old abandoned houses and pull out 40-30 coon a season.
Here's the secret, never get married, work at it all year and when the fall hits your ready. I have a good friend up in MI who runs Airedales and Jacks, he does very well chasing them.
The problem I have with the Jacks is there not bred tested many people just breed and claim the have a proven dog. Not even close, you go to England up the Fells and there running dogs with tight blood lines and no good terrier man in the US is going to be selling good workers unless you have an in.
