Turns out the CHIPmunk doesn't care for chips at all. We salted the mat with Doritos and I dropped a sample down the hole. Zippo. We rebaited with apricots and the Redhead got to see him twice and myself once. He comes up, surveys the situation, appropriates the 'cot, eats his way around it like a cabdriver doing donuts to the left and leaves with the center. (Chipmunks in the Southern Hemisphere presumably to the right)
Doritos will get trodden down into the mattage, cut up and hauled off by the Maine equivalent of the fire ant which is probably some kind of carnivorous whelk.
I could have won a bar bet on non-chipping chipmunks. Dang.
Update: Redhead says he scored two more apricots as soon as I came in to blog about chips. Damn these munks!
