My experience in las mina is similar to Rick's. There are a couple of sections of Las Mina, North and South, divided by I think it is called the San Vicente main street. The area I visit is lower middle class - which is lower than our lower middle class - poor working people. I had no problem during the day, but was accompanied after dark by neighborhood people. There were a lot of stray dogs around. It is mainly a residential area and not a tourist area.
