Situated in a historic building built especially for fishing, the owner/tenants are a friendly angling collective primarily focused on fly fishing. The few members I encountered on a visit were very engaging. This was my first time encounter with a casting pool. I loved it. Sequestered away from the main tourist draws in the golden gate park,it's a little difficult to find but if you are a fly fisherman, you have to go there. You won't regret your visit.
