This is the time of year (Winter) when I usually take stock of what-all I have, review what worked -- and what didn't -- and assess what I'll need for the coming year. I rework my tackle box and buy new hooks for spring and replace damaged rod tips and guides. I buy new line and fluorocarbon leader, but I don't spool my reels until I'm ready to fish. I'll check, clean and oil the reels and store them (how did I get so many?) I toss everything that I don't need, has rust, or is broken.
Between now and then, if I go on a relatively warm day, I'll just take a downsized tackle box with the essentials. As I get older I see the need for protecting my health so that I can keep doing this for many more years. Cold, windy, and rainy just don't agree with me anymore!
How about you guys? Do you have a winter routine? I do it now because I have time and because I like to revisit the previous year before filing it away in preparation for the next.
