i pretty much had to do this once for my job. it was raining hard all day and we had a piece of equipment that was covered in dirt (i had to take a shovel to it to remove some of the dirt). no amount of rain would have cleaned it. so i was pressure washing a bobcat in a downpour. the thing i always found funny was when i was doing it two joggers went by stopped pointed and laughed. i was being paid to do something that looked stupid and they were willingly jogging in weather that was fit for fish.
