Good luck.
I have access to a couple of places not in Fairfield County. My secret, none really. You have to know the people outside of deer season and before you ask permission. Remember if someone is willing to give you permission simply because you knocked on their door, it is almost certain that you aren't the first and won't be the last (kind of like women). So even if you get permission, you will have to share what are usually tiny parcels. But again, good luck.
