The 4th of July has always been one of my favorite holidays because 1) Summer! and 2) I've always been a little bit of an American history/ politics nerd (my B.A. is in political science with a domestic/ American focus.)
One of my favorite books ever regarding our first presidency is called A Sacred Union of Citizens and is an analysis of George Washington's farewell address. It's not exactly a beach read but it's not heavy lifting by any means. If you're interested in what Washington hoped for the future of our country I highly suggest you give it a read.
Happy 4th of July to all my fellow Americans, and a happy day to all my readers from other countries! (Especially my near and dear Canada. God bless you every day for hockey.)
