The Great Buffalo Roundup at Custer State Park

On a last minute tip, we changed up our plans to experience what we were told was a once-in-a-lifetime experience - the annual Buffalo Roundup at Custer State Park in the Black Hills of South Dakota. 1300 bison are herded by cowboys and cowgirls into pens for an annual health checkup.
Though it was cold and muddy, we had a wonderful time, and have a few tips for you if you're looking to give it a shot.
The Buffalo Roundup happens the Friday of the last weekend in September each year and is accompanied by an arts festival that spans the whole weekend.
