He says to bring a gun.
I have a love/hate affair with guns. I think hunting weapons, like breech loading shot guns and bolt action rifles are all anyone needs, and that having guns for self defense is just asking for trouble.
He said that guns are needed to scare off "banditos". I would think the "banditos" are armed too, and this would just esculate things. Plus, won't you be arrested if you are a forgeigner caught with guns? All it would take is one search at a border and I would be sepending time ina prison south of the border, and not for being drunk.
On the other hand, there are some very dangerous areas like Lima or Guatemala City. We can navigate around the rough areas we know about, but we can't know about them all.
I'm leaning against firearms, but I would be interested in hearing the opinions of others.
