As has been stated. Check with Douglas County and ascertain what zoning you are in. If in a S/D they may have by laws against shooting. Sometimes you don't have to be in a S/D just close and the zoning gets you.Then definitely check with neighbors and ask them to shoot with you. Be nice and friendly and ask them if there are certain times that they nap or have children that nap or what time they eat. many families like to sit down and eat undisturbed. If you start out on the right foot as it seems you are trying to do it will go a long way in keeping peace with neighbors.
