We do not live in a perfect world. Good luck with trying to get the exact time of allowing fireworks to be set off (around your time)..lol... When your child grows up to the age of playing with fireworks are you going to limit the "time" of lighting them off for your child???..lol come on, be realistic!...lol... Or maybe you will not allow your kid to fire off fireworks, PERIOD!!! Because there is always "another kid" trying to sleep, besides yours during the 24 hour pieriod, I have kids and fireworks never bothered them.. In fact it was a fun time to watch.. aaaaand my kids turned out fine.. Straight A's and Happy life!!!.......11:00pm is ok to limit the time. Why should people walk on "egg shells" just for your convienence?!?! And fireballs???..lol!!! Thats another story! You probably watch too many mystery shows!
