Patriot in front of me in traffic today

On my way home from the beach today, this truck was in front of me all the way up Lake Avenue to Lake Worth Road when I turned off. The flag says, "TRUMP, Keep America Great."  I could not determine what the flag below said but the date is 1789 which indicates the date of the United States Constitution when the 1st US Congress met and declared the Constitution in effect (9 senators, 13 reps). Obviously he is reminding people of the 2nd Amendment.
