Welcome! I'm guessing from your username that you might be another New Yorker. I was a New Yorker before my parents decided that Chapel Hill, NC would be a much better place to settle a few years before my father retired from Brooklyn College. So I ended up being a Carolina Tar Heel.
One way to find other Divas in your area is to start a Getting To Know You thread with NYC in the thread title. May need a few more posts before that section of Divas Only shows up.
Yoga is a great idea. My role model, Naomi, who was an Alta Lodge regular into her 90s did yoga every day. She didn't start skiing until age 40. My ski buddy, Bill, who is pushing 70, does the hour of yoga with an instructor before breakfast that is offered by Alta Lodge when we are there during late season with friends.
Naomi made this video in 2012 when she was about 90. I was lucky enough to meet her and ski a few runs with her for a few years. She was still skiing every weekday for at least an hour starting at first chair, longer if snow conditions were good.
