Right, not being funny, but MAN UP! I'm English, yeah. I've been to over 23 countries in the last 17 years. They vary in danger from the SUPERsafe Lady Elliot Island in Australia, which has less than 10 permanent residents, to the pretty damn dangerous. I spent 2 weeks in Costa Rica, the drugs run from South America to North. I'm pretty world wise. In Costa I was in San José for a lot of the time. The capital city. This is a city where ALL windows are barred. ALL of them. And the majority of houses/businesses/banks have men with shotguns, or assault rifles on 24hr watch, but no armed forces. Yet, at no point in my life, have I ever felt afraid. I've wandered through Chang-mai in Thailand looking for the source of live Jazz music I could hear. I've been cautious, yes, on alert, yes, but NEVER have I feared for my life. Just be careful and I have no doubt you'll be fine! Just eyes open.
My band'd be behind me all the way.
