Welcome to the board Carpe Diem!
Not everybody minds if you ask if they've caught anything (some folks are just cranky). When inquiring, be friendly and smile. If then person you ask just grunts no or looks at you like you have Lobsters crawling out of your ears (the cranky ones), tell them you hope they catch a big one and move on. If on the other hand the Angler seems friendly, go ahead and chat for a few minutes and ask questions (it's one of the best ways to learn about a body of water).
Keep reading the board and asking questions, you will learn alot here (I know I have), and you may be able to hook up with somebody for a trip or two.
Good Luck!, and I hope ya catch a big'un!
