Firefighter? Well Thanks for your service. 28 years law enforcement here, and always thought you firefighters were a bit crazy, then again I know firefighters that thought the same about us.
You've just become a member of an extraordinary group of people, and there is not a friendlier or more helpful forum for a blues guitarist anywhere on the internet!
Drop by often, join in the conversations. As great as the course materials are (and they are great) you will find a wealth of information (some of it good) and a lot of support and encouragement from the members.
You're going to love it here!
