where's that tagged sow???

I've tracked her three times since turning her loose. The first two times she was in roughly the same area, about a mile and a half from where I turned her loose. The place she's on is decent size (1500 acres or so) and doesnt allow any hunting and is prime habitat for hogs. They come down into the bottom on the ranch and feed at night. I tried to find her today with no luck. I didn't search real hard due to being busy and all. The tags have about a mile range. I have yet to make visual contact with her due to the property she's been on, but I hope to soon and find out if she's back with a group. With it cooling off this week I plan on tagging some more on different parts of the ranch.
