My car is parked about 3 feet from the side of my apartment. Once it gets warmer, the orb weavers select this as a choice spot for web-building. Nothing quite like being in a hurry in the morning and walking right into a huge web, complete with a large, very-annoyed spider sitting in the middle of it.
They also enjoy placing a web directly inside of my mailbox.
And just yesterday, one dropped down from the ceiling, right onto my ear.
When I get a house, I believe I shall have it hermetically sealed.
