I've seen this TB countless times (first of which was 6/15/07) but for some reason had never logged it. I saw it again at the "FTF All Star: Starting Line" event and got to finally log it. Grabbed some pics while there. Check'em out!
Just a heads up, it looks like someone grabbed it from you recently. You may want to grab it back.
Edit: on second look. I guess I did log it before during the big ammo can deal. Can I discover it twice, or should this be a note?
