PatC created a monster, 'cause nobody wants to see Don Simon no more they want AARR I'm chopped liver, well if you want AARR this is what I'll give ya, bad humor mixed with irrelevant info that'll make you roll your eyes quicker than a ~Z~ banhammer...
Somewhere in my basement is at tote full of all my HO stuff. In there I have an Athearn BN U30-C I bought ages ago to kitbash and superdetail based on the prototype but I never started the project.
Seeing this makes me want to dig it out and finally do it.
