January 29, 2021: CDC mask travel guidance ....
http://www.cdc.gov/quarantine/masks/...-guidance.html ..... is an historic United States shame this was not issued much earlier, like on March or April 29, 2020 ..... last year!
On May 1, 2020, Gov Chris Sununu held a two hour public announcement from the NH State House where he issued all the new corona virus mandates for NH businesses and residents.
