Depending how far north you were some deer yarding areas will pull deer from 20+ miles away. An area in Maine has studied deer in a particular yarding area travelling almost 50 miles.

In my experience it seems that deer seem to concentrate in less than 5 to 10 mile areas. I am pretty far south though. In Rindge NH where I hunt, the places we see deer each fall are completely devoid of any deer in the heart of winter, but about 5 miles away there is a yarding area in a thick cedar swamp that has groups of 40+ deer. I "think" this is where some of the deer I hunt go. If I were you I'd look for excellent "fall" feeding areas within a few miles of the yard you found as that would be your best bet for finding them I would think.
