I'd be sure to walk back and forth in front of the camera as much as I can. Heck, Id go there, walk in front of the camera (not showing my face) then change shirts, walk in front of it again 10 mins later and repeat. If he gets enough pics of what looks like different peoople he'll think 20 people are already hunting this spot and look for a new one. Little does he know its only one person and you won't be adding much more scent since you were already there.
