Mike, I was medically retired from the United States Navy in 2015 from an injury I experienced from a HUMVEE roll-over during my tour to Afghanistan. After being away from my family for three years, one year on tour and two years on medical hold, I'm home and I finally decided to learn guitar. Though I have not learned an entire song, I have learned a lot of riffs and things like that. I really enjoy your tutorials and wanted to say thanks. Don't ever think your efforts are not appreciated. Thanks again, Mark H., USN Retired...
