buildings collapsing in different regions. we've seen a number of fires as a result of gas. the international airport has been closed. i've been saying repeatedly that facades are falling off of buildings. we don't want people to believe that buildings are collapsing everywhere. they are not. some in mexico city have collapsed. we have a somewhat disturbing lack of information out of the epicenter area. i say that guarded. mexico is slow about reporting in these sorts of situations. there was an earthquake a couple weeks ago and we all remember, all of us of a certain age the earthquake in 1985. it was an 8.8 or an 8.9. that one caused widespread damage and calamity across the country. we'll continue to watch that.
