Traveling and Living In Central America
These sites about living and travel in Central America are run by people who really know Central America. The Guatemala site has more information than any other I have seen, including driving in Central America. Tom who runs www.xelapages.com has a site that blew me away.
The Panama site is run by Matt Landau, an up front guy and good writer. His web site is www.thepanamareport.com His blogs are top-notch.
Of course if you are driving to Central America, you will probably need my super-duper maps and road logs for Mexico's Gulf Coast.
