I only drove from Managua to Leon the first night. So I can really say about how Managua was. In Leon the people were friendly. I was carrying a DSLR camera and 1 person told me to hold on to it tight. I did how ever see a few guys that were walking the streets eyeing my camera a few times but I had it wrapped around my arm good and Im also a big guy. I really didnt feel unsafe at all during my stay in Leon. As in any foreign place just keep and eye out and be aware. Leon is a nice plan I would visit again.
