After you read John's book come and join
http://www.unitedbloodtrackers.org/ . We have over 100 members from novice trackers to guru's (like John) and everything in between. Everybody is very forthcoming with their experiences and knowledge and you don't need a dog to join. We offer several tracking workshop's per year in different geographic locations where we get together to train, work out problems and share experience's. We sell John's books in the online store but they're a little more than 25.00 because we're always trying to raise money to help the cause. We provide aid to members attempting to have Tracking Dog Legislation passed in state's that currently do not have such legislation. There's also a Breeder's Forum just in case you do decide to make the plunge. BTW- the photo of a Bavarian Mountain Hound in John's second edition is my dog "Vars".
