Check the section heading: "General banter - Non-SD related ... booze, birds and general "boys showing off" type stuff" My thought was it fell into the "boys showing off" category, although it's nothing more than the result of boredom...
As far as where to ride, it depends on what you want, how long you have, etc. Based on my personal experience, Hwy 7 out of Hot Springs, north all the way to Harrison is a great piece of blacktop. 70 west out of Hot Springs to 8 west towards Mena is supposed to be good but I have not personally ridden it. Most of my time on 2 wheels has been spent north of I-40. Let me know if you need some direction or even a guide up here.
