Dude really cares about building communities,dude is still working. Some ex-presidents, would have retired and chilled
Obama made a good point last year. He said being President doesn't change who you are. It just magnifies or put a spotlight on who you really are and it gives you more power to carry out your beliefs. We seen it with Trump, we seen it with Clinton in the 90's with the Monica thing. They were like that before they became President.
In Obama's case he did community organizing and worked as a community lawyer beforehand. He spoke to young people about community building during numerous open discussion town halls when he was President. Now this is just him going back to his casual interest roots that he's maintained all along.
I liked when they spoke about the playground that will be there, the outside concert area, the area to play basketball, the area where folks can bring out the grills and barbeque. Sounds like a place you can have a family reunion at.
