*Bows* Thank you sir
Give it time and start switching gears. Become a member of a local open club (target range, Ducks Unlim, OFAH, etc) to be seen as an engaged and responsible member of the hunting/shooting community. A couple fundraisers and chats over coffees and you'll be in like Flynn.
The cold shoulders from landowners I can understand. People pay a fortune in property taxes, property upkeep, food plots, ground blinds & tree stands, etc... they're going to be resistant to inviting strangers to join them. Stick to public lands to start and build up good graces... eventually you'll get some invites.
