Trigger warning:  Don't read my reply to Steve while eating your lunch.  
Howdy, Steve.  Yup.  That same biological phenomenon occurred.  I hiked later that day after all the initial gastro events subsided.  As I was hiking down during the sunset that evening, I stood by a cliff and answered nature's call.  As the beet's remains arced into the sunset, I noticed that the rich colors of the sunset and the unusual color my pee were one.  It was a very Zen moment to be at one with nature quite like that ;-)
