I recently received an email from someone who read one of my posts and wanted a location of an old one room school. It would have helped if they were specific as I have posted a lot of old schools. From their vague description I was able to figure out which one they were referring to.
After I saw which one it was I did not give out the location. I usually have no problem telling people where some things are if they want to visit them to take their own pictures. If a place is fairly well known I will tell people where it is. If friends give me locations with the understanding that I will not divulge the location then I will keep it secret. Vandalism and trespassing is a problem in rural areas and some places are on private land. Some explorers are fanatical about keeping locations a secret. Not me. Personally I like it when people go out to see things for themselves simply because some of these places may disappear entirely in a short amount of time. If I do not give out a location there is a valid reason. If anyone asks, do not get offended if I cannot give out a particular location.
