No exit

at state street, orange line (as can be seen above). not that i thought it was an exit in the first place, but now it made me wonder what is behind that wall! there is currently more police at the subway stations since they hypothesize that airports nowadays are so well protected against terrorists, it is likely that terrorists shift their focus to crowded subway stations. so, they every now and then take a bunch of policemen-machoguys and plant them behind a table at the entrance of a subway station. then they pick out people that they think need their bags searched (see previous post). besides, as extensively described in the newspaper this morning, they are testing gases in subway tunnels, as there is not only fear of bad people blowing up trains, but also of biological and chemical attacks, which are "just as lethal and perhaps harder to combat". what they do is releasing inert, odorless gas and particle tracers into the subway system and then they study how fast it spreads and when its gone again. apparently they already did that in decemeber, but since airflow changes based on weather, they want to see whether and how its now different....
well, it started raining yesterday and is supposed not to stop before tomorrow... will they also test it when its hot and dry again?
