Buffalo roundup at Custer State Park

Closer and closer they come.

Far away but getting closer, horseback riders and trucks are used to round them up and drive them.

There are two viewing areas, looks like they rounded up people, got them all fenced in real good! 

Here's the gang that sat still for an hour and chatted after the roundup, we were allowing traffic to clear out as there was only one two lane road for several miles to our viewing site.
The bottom picture is the sunrise, that's right, I was there for a sunRISE.  Once we were close (5 or 6 miles away) to the viewing area the traffic just stopped.  It started out dark and the sun came up while we were waiting.  We had to wait about a half hour for the gates to open.  so we could drive the rest of the way.  The entertainment was a pair of antelope on a nearby ridge getting it on.
We are glad we went but disappointed, we expected well over a thousand buffalo but there were only about 300.  There was dust but no thunder as the pamphlet led us to believe.  Bummer, but it's off the bucket list.
