When speaking to my Father earlier today, I suggested he get a large plastic owl to put on his deck to scare the birds.
Which begs a question. Is having a big plastic owl on your deck worse than bird crap? I suppose it is a debatable point. I would pick the owl.
I need to call and see if he picked one up, and I will let you know if it works. If it does not, I mght borrow it at Thanksgiving.
