The two places i would look are the local Federations if you want to join a club. I know there are a few down on the cape.
The BASS affiliated federation is at www.massofbass.com. They have a listing of all the clubs in the state and contacts.
The FLW affiliated federation is at www.massbass.com. Same thing thing as the other fed they have a list of clubs and contacts.
There is also a trail called Freedom Bass that runs a Cape Cod only tream trail if you know someone with a boat. They are at www.freedombass.com
Let me know if i can be of any help.
