There are several OU boards. The most irreverent and funniest is by far Landthieves.com. It is a much more contemporary board....lots of sarcasm and internal oneupsmanship. They are ok with visiting fans unless someone comes on with obvious vulnerability. It is patterned after Shaggy Bevo a similarly irreverent Texas board. Soonerillustrated, the Scout board, is very good.....an older more mature crowd. SoonerScoop is the Rivals board. Smaller group and older. Soonerfans.com is a very knowledgeable group. If I were a visitor I would pick either Soonerillustrated or Landthieves. By the way, Landthieves is what Texas fans call us;i.e. dirt burglars. This is all about the land run and the fact that the definition of a Sooner is someone who snuck into the territory as opposed to the Boomers who lined up on the Kansas line and went in when the gun (boom) went off.We are also referred to by the Horns as "Moblehoma"
that last sentence is funny, in that, I have always contended that the Mobile Home is the state bird of Oklahoma (with all due respect to the Scissor-tailed flycatcher)
