I don't understand my advisor

A labmate and I went to the field last year and found very few research organisms. We came up with a little project based on a crazy observation we made and also on what kind of data we could take that could be treated independently enough to do good statistics on and still maybe get a publication out of the trip.
Turns out, that data is really cool. And important. And it could be big. BIG. Or it might go somewhere smaller but I have no doubt it will go somewhere and that is great news for a field based, non-dissertation project.
Well, we are putting the finishing touches on the manuscript before it goes out for friendly review and had a meeting today to discuss the final figures, who to send it to, etc. My advisor comes out of nowhere telling us that he doesn't want to be on the paper.
WHAT?!?
I don't get it. It is his established system and field site, his partial financing of the trip, his time in the field and his input as we were re-grouping to come up with this project in the first place. He usually is not on publication from students' dissertation work but this isn't! As far as the work is concerned, he is very pleased and was the one to suggest sending it to an higher impact journal in the first place so it doesn't seem that he is distancing himself from it because it is of poor quality. Perhaps he is just crazy. Anyone have any better ideas or interpretations?

Wha huh?

As if my first class weren't exciting enough.... we were all stuck in our offices for a few minutes in the afternoon at the request of police.

We were let out. No one has a clue why or what happened but it appears as of now that everything and everyone is fine.

UPDATE: There was a medical emergency. The involved parties are being treated and expected to be fine. Sorry to worry you, Mom!
