What O2 (my brother!!) is referring to is:
A couple of years ago he and I were hunting a place where the deer could take one of 2 paths through a funnel. The path we DIDN'T want them to take was less than 5 feet wide, between a steep crick (creek to you city fellers) bank and a 9 ft high chain link fence of a neighboring property. If they went that way, we had no chance of even seeing a deer, much less having a shot. So we got tired of sittin there each day, knowing that there were scads of deer around but that they were probably taking the narrow path and skirting around us.
Well, the evening before our next hunt, I took an ole pair of skivies and I installed a, er, um, well, a, ah...well, I put a big ole skidmark in em. We're talking a Mexican food skidmark. A big ole BEAN BURRITO skidmark. Man did they STINK!!!!! So I put the skivies in a ziplock bag for the night.
Next morning, we got up, hiked into the woods, got to the "Y" in the trail and about 10 yds up the trail we DIDN'T want the deer to follow, I hung the "stained" skivies in a bush right on the trail. Then me and O2 headed on to our regular stands. Heh Heh...we didn't kill nuthin that day but we saw a lot of deer!!!!
