Hi Dennis, Glad you are a new Tennisopolis member. The TVTA drop-ins are held multiple times each week, but your best bet to catch the group are Sundays 12 noon. They meet at Cal HS. I think weekdays are tough for most since many are commuting back from Silicon Valley or SF and don't get back to San Ramon until after 7. There are still a few that meet Tu and Th at Dougherty. Come out one of these weekends to meet the group and get on the email list. That way you will know who is going to be at the courts.
