Her being an older person, I would hesitate throwing anything -- even water (lawsuit if she took a spill, fall, and broke her hip or get a heart attack or somethin).
I would instead insist on her washing all the dog poo, and while she's at it -- the rest of the truck, dry it, apply a good coat of wax, buff it, polish my bling wheels, armorall all the black trims, and rain-x all the windows.
I bet the local news crew wouldda showned up at the end of the 5-hours car wash..
That way, as many tree-huggers as possible wouldda learn the risk of messing with Hummers!!
