My electronic tuner has some issues but this handy website helped me tune my guitar in no time: http://www.guitarforbeginners.com/onlinetuner.html
I promised myself I'd practice guitar today and it was way out of tune. I also had to prune my finger nails so I could push down the strings. And once again all my calluses are gone from infrequent playing. It's always like starting from scratch for me in spite of my best intentions.
At some of the archery gatherings people sit around and play guitar. And I want to join them, I really do, but up to now I've never been good enough. But I'm too stubborn to quit.
