Scripps Memorial Hospital Encinitas emergency room doctors and nurses treat two to three injured surfers.
Encinitas is completely landlocked.
The article says that the hospital in Encinitas treats surfers, which implies that it is near the ocean. However, we don't know if the surfers were transported there from far away for some reason. We have no way of knowing if Encinitas is landlocked based on the information given. I think this confused the system because we have to make assumptions based on the fact that surfing takes place in the ocean.
