I am planning on riding out to Topeka and exploring the Riverside Motorcycle Park (aka Oakland) this Saturday, December 3rd. I'm not sure if there will be mud, but there will definitely be dirt, and probably some dropped bikes, and possibly some blood

Now I've got to believe that I'm not the only person on this forum that thinks like this, so if you ride a big bike and want to come play in the dirt like a kid with me let me know. I'm flexible on time but 11ish sounds like a good starting point.
Oh, and for the moto guys on the board, you should come out too. The more the merrier!
