Jeff,

To use your own often quoted tag line......"there are no cookie cutter answers".. It could be as simple as he didnt have to pee... Could be that he was just passing through and getting a whiff of what was in the area..

I typically don't pay much attention to scrapes, however the biggest buck Ive ever seen showed up at 10 minutes 'til dark and worked a scrape at 18yrds away, so who knows!
