Probably the easiest way to locate local clubs is to use the locator tool on the ARRL website at http://www.arrl.org/find-a-club
. Try to find a few that interest you and then attempt to find out if they have newcomer meetings that you can check out.
I found that most groups aren't too concerned about someone signing up right away if they're checking out a few different groups. Also, I would suggest seeing if they have an online newsletter or email list that you can check out to see what types of events they did in the last year to see what might interest you. Good luck!
