difficulties- Mex keeps using the same name for areas over and over making it very hard to rely on place names-would be like naming every usa town tom dick or harry -so hard to find trustworthy references- on a physical map this is much much easier but using the internet is like looking thru a glass darkly w blindfolds as it is -and here you have to keep manipulating the resolution for just the right res to show the right scale area and enough reference place names
