What a fun and interesting way to celebrate. I would have loved that golf course game. Heck, I'd love it now.
It seems to me there are two kinds of creatures: Those that want to run at a lit firework and bite it like the best dog toy ever, and those that want to hide under a bed and say dog prayers. I happen to have one of each in my house.
I can hear the distant booms indoors before, during, and after the fourth of July, but they generally are not very loud. I enjoy the sound. Maybe it reminds me of childhood, or maybe it makes me think that there is someone getting a little high off of their boom. Most likely it reminds me that there are holidays, and holidays are often lovely - even without fireworks. That said, I can sleep through a heavy metal band no problem, so that certainly plays a role in perspective :)
