I grew up fishing, skateboarding, surfing, wakeboarding, playing baseball, playing in bands and generally getting into trouble as a younger man. I still surf and skate and wakeboard from time to time and I'm generally amazed at how friendly, welcoming and uncompetitive anglers are. I very rarely encounter any "get off my wave" type attitudes, it's mostly people asking how it's going or telling me what bait is and isn't working. I've had more friendly conversations with strangers with a fishing pole in my hand than I have with a drink in my hand. What a relaxing way to get away from the computer and screens.
If you're interested, there are some great youtube resources for learning how to fish. I'm a bass fisherman so I'd recommend looking for videos and articles from bassresource, tacitcal bassin, and flukemaster. For anyone interested, bass fishing is a much more active form of fishing than most people imagine fishing to be. You're actively casting and retrieving rather than tossing a line into the water and waiting. Here's a video of a really great good ole Alabama boy doing some topwater bass fishing: https://www.youtube.com/watch?v=vvP0GBBiaLg
Edit: I live in New Jersey about 10 miles outside of New York City and fish for bass nearly every weekend. I've caught bass in Central Park before. There are fish in nearly every park pond across the country.
