Saturday I went back to many of the same spots on the southwest Oregon coast which I had stopped at Friday when I entered the state from California. These were taken at various times Saturday afternoon. Some, but not all, of the beach pictures have people in them as a size reference.
And Saturday afternoon I saw three more people wind surfing, this time in the ocean and not on the calm Pistol River.
I stood and watched them for 20 or 30 minutes. They traveled continuously back and forth up the coastline and out into the ocean and back near the shore. I only saw one of them wipe out that whole time so they all seemed to be very experienced. I can only imagine that this activity must be physically exhausting though it appears to be a lot of fun.
