Free face masks will be distributed today to Connecticut rail and bus passengers at various locations around the state.  The state Department of Transportation says under an executive order issued by Governor Lamont, masks are required on all buses and trains. The face mask distribution is being done ahead of the normally busy holiday travel season. Among the locations for the distribution today is Housatonic Area Regional Transit HART depot in Danbury at 3 Kennedy Avenue.  The distribution times are from 7am to 9 and 3pm to 5.
