Don't look, start your own opportunity. I went to the community building and found a day each month that it was free for a few hours, booked it and put up bulletins for free community quilt classes. The first class I had 60 people show up! I got some class members to help and we are still having the classes and it's been 5 years now. I did the same with a knitting group. I wanted to learn how to knit so I put up bulletins announcing the start of a knitting class/group at the community center. The first class 9 showed up and four of them knew how to knit and started teaching the rest of us. Check out free room at the local library, churches, community centers, or a business back room not in use. Some banks have free meeting rooms too. Start your own community service, never know what will develop.
