Hey Bryan, can a person hunt that little creek area about a hundred yards north of the Mission south of town on 77? And I just looked at it on Google Earth and the bridge dips down into the water. The got their water from that creek and I bet, if it isn't inside the park area, that it would be a great place to detect. Looks like the state park boundaries are in the river/creek, so better not get on the north side with a detector. Wasn't the actual battle field northeast of the mission a ways? Like several miles?
