The people of the United States are with you!  For now our prayers and encouragement; soon, whatever aid we can give.  I love beautiful Mexico City and am deeply saddened at this tragedy.  Am also encouraged to see citizens immediately rolling up their sleeves to search for the missing;  even businessmen in dress shirts and ties wielding sledge hammers!  May God bless you all and keep you safe.  Our condolences to the families who lost loved ones and friends. :(
