I'd tell her don't park under that street lamp or telephone line anymore! Look up before you park.
... Good call to get it off asap though. Maybe hit it with some quick detailer before you go swirling around with a wet rag next time.
Actually she was close to an overhead power line. She moved and no problems since.
The mess was pretty soft when she arrived home, it came off easily with warm water and a sponge. Finished up with Megaiurs detailer.
