I live in Dunning. 25 years. Love it here and highly recomment. Quiet, peaceful, low crime rate. Most crime is residential/garage break-in type. We had our first murder in 20 years. It was husband/wife murder suicide.
Unfortunately as a licensed real estate agent, we are not allowed to voice our opinion as to what we feel is safe, seeing as everyone has a different meaning. Your best bet is to do what Manuel mentioned, go to the local police department, and visit the area at different times of the day.
