Fish!
Each year I buy a fishing license. In part to fish, and in part to show support for fishing. This summer I have been doing a lot more fishing than usual. Part of this is due to having the Kruger Seawind, which is a more stable fishing platform than any of my kayaks. the other is that this winter I was outfitting the Kruger with a stern pole light that uses the same base plate that is used for fishing rod holders. So, I installed one more, and got the rod holder part as a present.
I also discovered the "Gulp!" artificial lures by Berkley, which seem to work well in the areas I paddle and fish.
Only problem with fishing - my mileage decreases significantly! :)
