I just picked up a map at 3 vets in vancouver that has all the locations for the whole georgia straight and it has all the local markers you read about on these sights (ie. t 10, sandheads, q 62(bellbouy) hole in the wall) its a pretty good nautical map aswell and includes long./lat navigation. I'm not completely sure how to read it all yet but it will surely help you out and give a good idea of the areas. I'm sure other tackle shops would have them too. hope this helps
good luck morganic
