In the spirit of Cadillac Mike's post I'll give you a little hint on mine:
There's more than one Hudson in my life. While the rail version takes precedence, I also wanted to make sure that I didn't forget my automotive background. 'Mellow' comes out of family lore about a specific Hudson Hornet, light yellow in color, with an attitude -- similar to a famous Plymouth named Christine.
