What grinds my gears are people who change their baby at the ramp and then leave the dirty diaper in the parking lot. I watched this happen a few years ago when a woman changed a baby, pitched the loaded (and I mean LOADED) diaper in the parking lot with a trash can not more than 30' away, and then proceeded to get in the boat with her husband and head upriver. I always carry nitrile or latex gloves with me in case I come up on a traffic accident so after they left I put them on, picked up the diaper, unfolded it, and then proceeded to smear the contents all across the windshield of their SUV. By the time I was finished it looked like the windshield of an off-road racer who had just hit the largest of mud puddles. I then put the diaper under the windshield wipers and left a sticky note saying, "You forgot this."
