I think I know the answer, but I'd like to hear it from someone who knows for sure. I had a station that was about 3-4 miles away for a time, but it just disappeared one day. I'm assuming these are just ordinary folks with a weather station in their yard, etc. who can put up a station, and take it down as they like. Is that correct? And also, I assume that people with these PW stations can choose whether or not they will or will not be reporting their data. Is that correct?
