Confession time: I wear cotton too AND I have a Garmin Nuvi. wink But I know the limits of that GPS and it doesn't bother me to hear the sweet but animated voice say, "recalculating" as I disregard the route it has selected and instead continue the way I know. Too many traffic lights that way and the construction zones suck.

There are lots of things the Nuvi does well, but it doesn't necessarily "know more". Thinking the little box on your dashboard knows your car won't get stuck in the snow ahead can get you killed. GPS units have their limits and so does cotton.

Cotton is very comfortable when you're out of the rain and the temps are good, but when it gets wet and the temps go south cotton can be a killer. But I still wear cotton. I also wear wool and cool-max and polyester fleece. They all have their place and some are better than others at times; at other times they reverse and the others are better.

Wool socks are good all year cool
