Love the Hatha class here... Stephanie is a great instructor and sometimes a slow class is just what you need after a burnout day.
Take Tony Porter's drawing class. Great instructor. It's a great place for those with little experience to explore their creative curiosity.
A great variety of classes. I recommend Bob Horn's Figure Drawing -- he's a great teacher. Read more.
Just past the baseball fields you can take part in free Yoga and Pilates sessions led by an awesome local instructor on Sunday mornings throughout the summer.
