Taxman - I' m on crutches too (broke my ankle), so I know how you feel! I get my cast off tomorrow, so I get to see how well i can walk. Hope you' re up and walking again by deer season!
Hope you are able to get a pic so we can get a better idea of what you' re talking about. A pic of the log pile would maybe help as well.
It' s not impossible that it' s a deer rub - might be a huge buck with tall tines and sticker points everywhere
