Things to see near Camp Robinson?

I just returned from Camp R., but didn't have a day off to get out and have a look around much. There is a cool little Military museum on post with a large weapons collection on display, donated by an officer named Yeater, and there's a fishing pond. There are historical sights such as Central High School brought into prominence during the4 Civil Rights struggle in the late 50's. There is a Civil War cemetery nearby, a battle sight
at Jenkins Ferry and others. There are cool shops on or near the Arkansas river, downtown. Here's a link for more options: http://en.wikipedia.org/wiki/List_of_National_Historic_Landmarks_in_Arkansas
