You want to play? You need to find a game where you can fit in.
I suggest you start by checking the list of games maintained by wheretheswindsblow.com. This link is directly to their page for groups, but they also have listings for tournaments and for finding a teacher in your area. I know that trying to learn from a tutorial is not for everyone. Of course, even when I am involved in teaching in person I always suggest that the participants use the tutorial as another source since it can help reinforce what we are covering in the class.
If you don't find a group to play with at this link, I am sure you will notice that one source of possible regular games for older players would be Senior Centers. In the area where I live many of the towns and cities have regular games in their senior centers which welcome new resident players who know the game. Most of them are not set up to teach the game, however.
Of course, another way to find a game is to get some of your friends together and learn to play. If you do not have anyone with experience, it may take you a little longer to understand the game, but if you can get started playing using this tutorial you will be off to a good start. You can always add new players who learn using this site.
I have a few sites in the Dallas, Texas area listed here for now but will remove this as soon as they are listed at wherethewindsblow.com.
