Hello from NorCal (Bay Area), I first found this excellent site a few years ago while trying to gain knowledge on my favorite Oakley shades. Recently I've become even more of an Oakley guy so I decided to finally sign up. My first exposure to Oakley was when the Marine Corps issued me a pair of M Frames 2.0 before an Iraq deployment. I also found a beat up but still wearable pair of Half Jackets out there too lol. These days my Oakley collection has expanded, and I rotate between them, Smith and ESS shades every 2 weeks or so. Hoping to expand it further, and attain more knowledge.
