After listening to the nightly news (I get NBC nightly news on a podcast now) I think the feeling of helplessness finally sank in. I was driving at the time into work when that feeling sunk in.
The first thing that I did was pray (which is the first thing we should always do). The next thing will be to donate. In my previous post, I gave four links for people to link to and there are more. At Instapundit, Glen Reynolds has started the donations blogburst as people trackback to him. There are quite a few. I would suggest going there and checking it out.
