Of all the PA color schemes he could have picked (*cough*warbonnet*cough), he chose that.
A very attractive scheme was chosen - that PA looks beautiful in her NKP paint! Mr. McCormack is doing the legwork, Mr. McCormack gets to choose how she is presented. Perhaps body wraps could be made so we could enjoy roads like Wabash, Pennsy, EL and others.
Some patience will yield a PA in ATSF paint down Texas way: http://www.museumoftheamerican...s/ProjectALCOPA.aspx
Keep in mind, the other two PAs in North America wear some rather interesting paint shemes, far removed from their original paint. I wonder what the PA in Brazil looks like these days...
