I am glad that besides just playing during summer break, the kiddo attends summer school and his mama also brings him on excursions to a gem panning cavern and marble factory.
He recently visited the money museum at the Federal Reserve Bank to learn something about money and to check out the many exhibits. They opted for a self-guided tour. Admission is free and no reservation is required.
I hope the kiddo managed to gain some knowledge about the value of money. He once told me that he had a lot of money in his piggy bank. He wanted to give me seven dollars so that I could buy a house near his home and I don't have to be always flying in to see him.
