so, where I live people just love to illegally ride 4 wheelers

so, where I live people just love to illegally ride 4 wheelers on the road. they always stir up my dogs and drive back and forth and refuse to stop when we try to get them. today, my puppy that wasnt even a year old, got hit and died. he's usually very good at not going down to the road. except when it comes to people riding 4 wheelers ILLEGALLY. it's loud and they usually go slow enough to alarm the dogs and they start to chase. i feel like such crap. i wanted them to be put in the pen but everyone refuses to do so. and i havent spent much time with him since he was born- and even when i have, it always consisted of him and his brother playing on my bed around me. especially lately because of work. and now i have his brother and im going to spend more time with him. and that makes me feel worse because Pi would have loved more time with me. he would have loved to sleep in my bed with me more. he was so loving. and i didnt really do that with him because he had his brother and they were always playing outside and i was always working or sleeping. all i can think of is his sad puppy eyes looking at me from outside the door, wanting me to come play or him to come inside to play and its breaking my heart. i didnt deserve him.
