I'm headed up to Ogunquit, ME for labor day weekend with my wife and my mother-in-law

. I'll need to head out and do some fishing to maintain my sanity. I have done a little research and apparently there is a ton of water to fish up there and the tidal changes are huge. Having never been to ME before, I am looking for any info that can get me started in exploring the waters of Maine. Tackle shops, accessible fishing locations (no secret spots), or any other info or tips you think are beneficial would be greatly appreciated. Thanks.
Jim
