Even if you can't get out to play with other people (or if, as in some parts of the country, the nearest pickers are out of reach), you can play a little each day. You might be surprised at how soon you can get really rusty if you aren't playing-- sometimes, four or five days can set you 'way back. But even 15 or 20 minutes a day can keep your skills up to a tolerable level.
That photo above was taken in 1971, when I was in the Air Force at Del Rio, Texas for a year. That whole year I never found anybody to pick with there, but I tried to play a little every day I could. And I not only held onto what I could play to begin with, but made some progress as well.
Of course, it's always easier to practice if you have other people to play with. But if you don't, our Slow Jam and Picking Up the Pace DVDs are made just for you. You can also play along with Murphy at the end of nearly every lesson on our other DVDs. And I have heard of people even practicing with each other on the phone! However you do it, don't forget your Holiday Picking.
