Today, we honor the life and accomplishments of Martin Luther King Jr., one of the most influential civil rights leaders recognized for advancing the rights of minorities through a campaign of civil disobedience. Multiple #NationalParkService sites honor MLK Jr., including MartinLutherKingJrNPS in Georgia, SelmatoMontgomeryNPS in Alabama, and, of course the famous Martin Luther King, Jr. Memorial in Washington, DC. Don't forget - all National Park sites have free entry today! #MLK #MLKJr #NationalParks #FeeFreeDay #MLKDay 📸: NationalParkService Image: The Martin Luther King, Jr. Memorial lit up at night
