There is a lot I could say about the state of the Republic (note for the poorly educated, we are NOT a democracy), but I will skip it and play Gunny Mormon for a minute.
"... Be careful out there!" A line I loved in a tv show many years ago, and all the more important today.
First, the 4th is, IMO, one of the top holidays to bring out the amateurs (second only to St. Patrick's Day). Watch out for idiots, and if handling fireworks or around those who are, please do listen for words to the effect of "hey y'all, watch this!" and react to protect oneself. Please don't be the one to say it. Keep an extra eye peeled when driving. Me, I hope to watch fireworks from a comfortable distance where I can smoke a cigar or my pipe lounging in comfort away from crowds.
Second, there is a lot of chatter about the potential for terrorism (workplace violence, random acts, etc. in the governmental parlance). Honestly, I'm surprised we've not had more and would not be surprised. Be prepared, protect yourself and your own, and do what you have to if anything does happen.
Finally, enjoy. The Great Experiment is in crisis (IMO), but is still creaking along. Savor what there is, and take a moment to re-read some of the finest words on governance (and self-governance) ever written in my humble opinion. They are the cornerstone of the Republic, with the Constitution being the foundation.
Be prepared, but enjoy the holiday.
