Yep. You must be new to the boards. Everyone here knows there aren't any trouts in the Black Hills!!
google Hill City,SD or Black Hills tourism. In addition to Al's articles, you'll be overwhelmed. Don't know about shooting prairie dogs though. Most of the ones I've met are on State grounds (parks), and I believe the rangers frown on that.
You might also invest the few bucks needed for the Steve Kinsella book, Trout Fishing in the Black Hills.
Trouts don't live in ugly places.
A friend is not who knows you the longest, but the one who came and never left your side.
Don't look back, we ain't goin' that way.
