I came across a new blog recently which focuses on El Salvador. It's called The El Salvador Gringo and has posts which focus on information for gringos traveling to El Salvador. According to the blog:
The El Salvador Gringo is a frequent visitor to Central and South America. Watch this site for the latest in rumors, news and the latest hotspots in one of the fastest growing Central American countries.
Recent posts have included residence permits, hotel and restaurant recommendations, places to visit, and local customs. The blog is part of a "Gringo" network of related blogs covering several countries in Latin America.
