Here, check out this tread.:
http://www.clubtitan.org/forums/showthread.php?t=55456 It will show you lots of pictures of Titans as well as show you their take on the big track day. I'm there as well!
Edit: I had said the Titan boys were cool but they've turned bunk again badmouthing me on that thread. Only updating here so that if anybody does go over there and look at that thread, they won't be baffled by the negativity and immaturity now there after I had said they were cool (in other words, they WERE being cool, now they're not).
