I have a pair of polarized Oakleys and another pair of Serengetis I use for driving. A couple pairs of old-skool Serengetis that I hang on to for sentimental, if not fashion-based, reasons. Some small-frame Wayfarers for when I'm channeling the Blues Brothers (just like Chuck Taylors and Levis, these things come back around every few years). Hmmm...what else? A pair of Ray Ban Outdoorsman aviators that date back to my USAF days. A pair of Arnette wraparounds that saved my left eye when I slipped on moss and face-planted on a river rock during a fishing trip last summer. They're now bent beyond use from the impact, but I haven't been able to bring myself to to throw them away yet.
I've been checking out the Juan Pablo Montoya Oakley Spikes, which I have yet to find locally for try-on purposes, but I like how they look on him.
Now that I have my vision back and don't have to wear glasses/contacts any longer, I'm digging the sunglasses scene again
