a place like that is a gem, it can and will get ruined very quickly if word gets out.
Agreed. I have leaked some good locations before for native trout, and had the spots ruined. (People always there, trash everywhere, probably some poaching, etc.)
I know of a dozen or so tiny streams that hold native brookies from when I was really into hiking in remote spots. I'd go to a new town every week and hike through whatever woods there were nearby with a 6 piece travel fly rod. If I'd find a stream, I'd mark the locations on map (this was before Iphones and Google Maps!). You'd be surprised how many streams there are in MA that hold native brookies.
