Lance,
They have taken up residence at the departure end of 29.

They show up in the evening just as the sun sets and hang out over night. I chased them away one evening doing touch and go's. (They banked left, I banked right) I think as much as it'll PO the campers it would be a good policy to taxi the length of the runway if you are going to be the first departure of the day on 29 at O22 Columbia. Also, we have had a number of plane versus deer incidents early am late, late evening.
I was in Las Vegas for the weekend and I missed the 170 fly-in. There were still a couple left when we got back about 11:30 am on Sunday. None with shark teeth though...
