I am going to be in Penn Yann on Keuka lake for one day quite soon without access to a car. Rather than rent one for a day, I am thinking I'd rather go on an organized tour. The ones I see online are wine trail tours--several of which are private with a hired driver. Being by myself, I would prefer to join a tour with a larger group. Has anyone gone on a group tour they could recommend? A non-wine oriented tour would be fine as well if any exist.
