It sounds like you have an idea of where they do bed even though its off your property. Do you use a site like Google Earth? If so, do some homework to try to pinpoint some possible bedding areas on the adjacent properties. You can learn a "lot" from studying aerial and satellite photos. It also sounds like you have a pretty good idea of the trail system on your property. If so, backtrail those particular trails you saw activity on this season and find some new spots that are closer to the property line so that you can intercept them a little earlier. Deer move slowly in the afternoon working their way from bedding areas to feeding areas, esp. mature bucksand just a small move closer to their bedding area can buy you some significant time. With the info. you gather from Google Earth and your scouting expeditions try to find yourself some type of pinch point to set up at. Who knows, maybe the trails you've been watching intersect near the property line.Most property lines in this country are some sort of feature like a waterway, field edge, rd. etc etc. There's usually lots of pinch pts. along property lines. Good luck.
