coco,
I prefer a local club, as opposed to a national group.
Here in the tidewater area there are numerous anglers clubs. I've been a member of the VaBeach Anglers Club for about 6 or 8 years.
I definitely think it's a good idea to join one.
I would look for a club that has some fisherpeople that share some of your interests. You'll also have the opportunity to learn other types of fishing and techniques. Some groups are very family oriented as well, with yearly awards banquets, oyster roasts, activities for the kids and such. Most clubs also participate in and sponsor various tournaments that you'll get the opportunity to fish in.
I think it's a good way to go!
