I have killed about a half dozen rattlers in the Badlands. My nephew has been hit twice, but was wearing snake boots both times. Last time he was walking along a small ledge and he was hit within a half inch of his boot tops. I have been hunting by the Maad Daah Hey trail, but in many areas I will not walk in the trail. On the west side of the Little Missouri near the Elk Hornady Ranch I noticed the trail was worn nearly a foot deep. Walk in that and a snake will hit above the boots.
I have been bow hunting the Badlands since 1980, so I guess my average is one snake every six years. Years ago I covered five to ten miles a day. In that time I seen most on the road while driving.
