Glad to hear the day ended on a good note for you....I personally don't do much fishing where I have such problems....try to walk in to where such psuedo fishermen are too lazy to go....littering has always been a problem in the park....I will always honk when something goes out the window just to let them know someone is is always amazing where trash will show up even in the backcountry....your comments about picking on a stranger reminded me of when I first went to roommate warned me not to pick on the little guys....they were the ones who grew up having to protect themselves and usually were the toughest.
