Everyone had already exited the water when we started mousing that first night. We were standing on a sand bar by ourselves.

The second night there were a couple of fellows on the far left of us, but as soon as my buddy landed that first fish and they got a look at it they exited pretty quickly.
The San Juan River is a great place and does tend to get crowded, but it seems that most fisherman have their own favorite spots and usually stay close to them.
