Fly fishing (sort of) newbie looking for some guidance

I am experienced saltwater fisherman who is now a year round North Country resident. My experience with reading saltwater flats, big flies, and 8 wt. rods is not very useful here so I feel like I am starting over from scratch. I am looking for some help with transitioning to cold water fishing, fly tying, etc. Also, are there any local fishing clubs where people gather to share their experience?

Thanks in advance for any advice.
