I'll admit that you had me scratching my head for more than a minute with "RCSB" (even checked the acronym thread), but (thick headed as I am) I finally figured it out. Even so, it's only fair that I give just little payback, so here it is. About 15 years ago the CPS in my FPS went out and left me stranded just North of Doodah. To complicate the matter I was hauling a 4-horse GN at the time. The towing bill to town was horrendous.
Have a wonderful day.
