None of those here yet. We also haven't succumbed to the trash-heaped roadside memorial, at least not that I've seen. There are crosses at many crash sites, which I think were originally placed by MADD (mothers against drunk driving). I don't know that they do that anymore.

There has been a rise in the placing of (thankfully temporary) heaps of flowers, toys, notes, at sites where some horrific death has occurred, mostly in towns. I blame the British, having encouraged this stupid (IMO) custom after the death of Diana.
