LOL. worrying about the cost does seem silly. It's another hobby.
I'm in Ontario, so it's 2 lines per angler. Mostly I'm fishing solo, so that's 2 lines total.
I spend a lot of time in the winter dreaming and planning about fishing when spring returns. That leads to trying to perfect things which are probably just fine. If it was boating/fishing weather I'd be busy doing, not dreaming.
