a couple of years ago, I was with my parents on a long trip in their MH and my father became quite ill (high fever and non-responsive). I used my cell phone and called 911 for the ambulance. The operator/dispatcher knew I was at a city park, but apparently didn't know there were RV parking spots there. Her concern was where in the park. I finally convinced her that the responders would see us once they entered the park, as there were only about 3 RV's in the park that day, and I would stand outside to ensure the EMT's could find us. I am pretty sure I didn't tell the dispatcher where we were as I couldn't remember the correct name of the park. I remember she asked me if I was in ____ park, and I did tell her yes, that was where I was.She had to have used the GPS function of my cell phone. all this being said, we were in a park in the middle of a major city, so it is likely they have better 911 center than some rural counties I have been in.
