The back of my yard borders a well drilling property . I know the owners and talked to them about me pracicing in my yard. I know the hours if thier operation and can hear when thier gate opens . I check before and during shooting. Even though there is a good amount of trees between my target to thier fence I don't shoot if thier are people there. After church a friend stopped by and wanted to shoot. I checked and all was good . He shot 4 shots and it was my turn I heard the buzzer ring and gate open. I went behind my target and looked. A guy came in and was cleaning some equipment. Even though he wasn't in line of fire I told my friend no shooting . He was mad and said I won't miss my target . What ever happened to safety . We can shoot bows anywhere we feel is safe. We have no limits on hunting distances from houses with archery but if things like this continue a lot of guys like me will lose the ability to shoot regularly and places we hunt.
