Hennipem, Ramsay and Dakota counties all have excellent GIS maps with all sorts of interesting information about properties. Public records are sooooo accessible now. No skulking around in basements that say "beware of tiger" on the door. Sometimes. No one claims to have completely accurate information and some people are better at covering tracks.
