Here are a few pictures of said crack. I just got the bike back from the bike shop, after all is said and done, Trek won't warranty, not a surprise. They want me to ship it to them, and for only $200 they'll look at it to see if it can be repaired. If not they'll cut a big chunk out of it and send it back. Shop says, mark the crack, ride it, watch for it to get worse. If it does, then action might be needed.
I'll take door #2.
Quick overview of where it is, you really can't see it in this picture, but it's right there in the middle.
It doesn't actually look this bad, I oversharpened this photo and jacked up the contrast.
