This sort of thing is very upsetting, if you have any kind of heart it makes you speechless. I was in the area back in 1998, and stayed in Slidell Louisiana, which is a town on the banks on Lake Ponchratrain (sp?). It is also the town where my great-great-grandfather was born. Now it doesn't exist. I passed over the lake on I-10, which is a very long, very scary bridge, and now that doesn't exist.
When I moved to New York in 1997, the first thing I saw of the city were the tops of the World Trade Center. Now they don't exist.
We fool ourselves if we think that anything is invulnerable, impenetrable, immortal. Things change, the best we can do is adapt, move on, build on.
