That link I posted earlier has a little info on the Pig Trail on the "things to do" tab. The Pig Trail is pretty amazing, but it depends on how far you want to ride. I just did some figuring on google maps, and if you ride from Hot Springs, through Ozark, all the way to Fayetteville, it should take just over 4 hours, one-way. It would be a beautiful ride, though. It would take you through two nat'l forests and two or three different mountain ranges. If you like wine, there are two or three wineries near Altus, about half-way between Hot Springs and Fayetteville. There are a few good restaurants in that area, too.
