I will be traveling by myself for a day trip. I will be returning before dark to Andover . I have done some research on the safety of Salem an have read some articles in the Salem patch that indicate there has been an increase of muggings and pan handlers over the last few years. Is this something that I need to worry about in the tourist areas of Salem? If you could please give me an idea of where not to go in the area alone I would truly appreciate it!
