[Hayman]

I finally got a little time to bring it around to the shop. Today I cleaned about five lbs of mouse nest/crap, shredded papers, and dirt out of the cab and under the hood. The engine is not stuck so I'm almost certain I can get it to run. In blowing some grease off I noticed it has plaid rocker arm covers. I'm sure this question has been discussed many times, but if someone would mind, what is this about? The first small steps are taken.
