- I find it quite disturbing that news about the "weather" balloon seem to be more important then the toxic train crash catastrophe in Ohio. Animals dropping dead as this ecological disaster unfolds really makes you feel sad. Regarding the train infrastructure in the U.S. the build back plan should be imposed and the reverted legaslation regarding brakes reinstated.
