I echo your thanks to those I've learned from, and also would like to say "you're welcome", as I've shared my Quincy experience readily with those who've asked. As I've said in recent posts, I am no great bass angler, but I've caught a lot of 14"+ sized bass (almost all LMB) at Quincy this year. I've caught 2 fish 18", and 5 at 16". As a newbie to bass fishing, I credit the generous people on this forum for my success.
That is what the forum is about. Fishing, and comraderie. That's it.
Be aware that Quincy is a sensitive place to many local bass fisherman. Quincy may be the best LMB fishery in the state. It sounds like you're C&R anyway, and that's great. Just be aware that if you're lucky enough to catch a really big bass and choose to keep it, a lot of people won't be psyched to hear about it (I'm not one of them).
Personally, I say do what's legal first, and what you feel OK with second. Keep a legal catch if you want, but think about it. Again, it sounds like this isn't an issue for you, and that's awesome.
Anyway, Congratulations on your success! Quincy definitely pays off if you put in the time and research. I hope you continue to post your experiences. Keep at it, and you could conceivably pull a 5-pounder out of Quincy.
BTW...I come from a trout background, too. Using fly gear for bass is my new favorite thing, especially this time of year. Get bass-plug flies and fish them pretty much like you would with spin gear. It's really fun. I've gone all the way up to 0X leader on a 5-wt. and haven't had any leader-shyness or broken lines. I've had a bunch spit me out, but that's still fun. I've usually found them on the eastern bank towards the "inlet" (the south end).
What a great place to take a kid! Happy fishing!
