My Dad expressed to me that "Americans should do more for their country than just pay their taxes". If its putting your regular life on hold (and at continual risk) while serving in the military, being a firefighter, being a law enforcement officer, supporting these people protecting us, or just making a community contribution, somehow. He was too young for WWI, and had a sizable family by the time America entered WWII. So he became a civilian air raid spotter, and then was a reserve policeman in our small town for 30 years.
America will continue to be great only if we all continue to sacrifice to support it. Happy birthday USA to all of our ancestors who gave us this great Constitution, and to all of us who keep it going!!!
