Jayman:
I can honestly say in my entire fishing career here in NY state that I have never seen a green sunfish. (its hard to catch them on muskey plugs

) But seriously I have never seen one in all the fishing I have done throughout NY state.
Lavarock:
You might want to look through this list for fish suppliers. It was the 2003 listing from Cornell and I am not making comment as to which one is good or not but here it is for your review:
