Welcome aboard. You will indeed finds loads of information and help on these forums. There are lots of helpful and courteous fisherfolk on this site.
I grew up in Braintree and I now live in NH. Let me start out here with a couple of questions:
1. Are you more interested in saltwater or freshwater fly fishing (or both)?
2. Are you interested in using the forum to learn about choosing the right gear for the task? Or do you already own a rod and you are just looking for advice on where and how to fish?
Answer questions 1 and 2 above and I can help you out. I just need to know where to focus when I start dishing mediocre advice!
I also fully encourage you to use the search feature of the Forum. If you use the search tab at the top of the page you can learn lots about fishing in your home waters.
Again, welcome aboard!
