So let me get this straight.....
You have to much time to your self and no kids to suck up your disposable income...WAHHHH!!!!
Seriously, take up ice fishing. It gets you outside, you get to fish, you get to drink, you get to eat, You get to sleep nights, gear is cheap ( a good jigging rod is $35 and a good tip-up is $15), The company is good.....you can even bring the wife if you want
it's a natural answer to winter for a fisherman
