Oh Haiti...already the poorest country and now hit with this. Earthquakes are so awful.
Yes, donate right away to the Red Cross and other worthy groups, but please also think about preparation at home. Do you have one gallon per person, per day of emergency water? A "go" kit? Do you know how to shut off the gas? Enough supplies to survive for 72-hours on your own?
In San Francisco, I encourage you to join NERT and be trained to help in the next big quake at home.
