One thing that is absolutely vital--at least for me--is my glasses. I'm farsighted, which of course means that I need the specs to read, tie knots, tell oat soda from creme soda in the cooler, etc. I bought a few pair of cheap magnifying specs at the discount store for 88 cents each. I fixed each of them up with a neck cord, and I do mean cord. None of those fancy glasses-snaffler things, just some twine. Point is, I don't take my prescription bifocals on the water. They stay safe in the car and I hang a pair of cheap cheaters around my neck. Of course, if it's not night, I'll take a pair of polarized glasses too. I feel better wading, leaning over the water, crashing through brush, dodging pokeweed javelins thrown by my son, etc. knowing that whatever happens, I won't break or loose my good specs. I use the cheapos elsewhere, too. I took a pair to the amusement park with the family. The daughters were scandalized, once again Dad is an embarassment to all!
