No sarcasm this time. This is a very good post.
It sounds like you don't have a lot of others to fish with, but you have to be extremely careful if you're out alone. Especially in waders. Brothers said it perfectly, "if it doesn't feel right, don't push it." I'm older than both of you, and have gotten much more conservative with my limits (when I'm actually fishing these days).
As far as sharks, they scare the **** out of me. Not gonna lie. I used to never think about them when wading around at night, but now it's all I think about. I honestly don't like to stand in the water beyond my waist at night any more. I will walk out and hop up on a rock, but not standing in the water. Don't give a **** what anyone I'm fishing with thinks about it or says. I know the chances of anything actually happening are incredibly slim, but...
And relationships. Yeah, fishing is not good for relationships. I have really had to take a big step back the last couple of years. Became way too much of an obsession. If I was single, no kids, I wouldn't really care, but I'm not. Just make sure you keep your priorities straight.
Good luck. Have a great season and be safe!
