hey everyone, welcome
I agree with Anij and think they gave a very respectful and clear post about learning from fluent/native signers. Am in my 30's, I'm new hoh and learning ASL. Some years ago, I had worked with Deaf kids in a recreational program for a few years. Was a college job and I graduated and went into my field - but always retained the interest to learn more.
ASL is by definition a visual-spatial language, with local and regional differences. Things like facial grammar, even slight body position and other very specific visual things that you can miss without a real live person, are very important.
Anij gave some great references - here's brainstorming of mine- even if there isn't an active an open d/Deaf club, Deaf Coffee, or Happy Hour near you, the odds are there is a generally a church service that may offer some ASL gatherings, or a Deaf school that you can contact to see if they can give you any leads in the ACTUAL local Deaf community. Or there may be a d/D/hh center, adult group home with fluent staff, local or regional Deaf/ASL studies program where they may be able to connect you with someone. You could even try the local school system's Deaf ed, Exceptional Ed placements <the reference to "Ex Ed" is purely a way to find Deaf contact for this poster; I understand the issues surrounding that concept> - asking for resources in the DEAF community; try the local university's Accessibility Center <working with Deaf college students>.
Good luck-
