Do these areas of Mexico include counties in California that have been ceded to Mexico, like the one I fled about 10 years ago when I retired?
Amazingly, no. The first state listed is along the South Texas border and the upper Golf Coast. The other four dot the pacific coast and are very likely to be overrun by the drug cartel as import or export points.
Two things everyone agrees about Mexico though - a) do not drive anywhere after sunset and b) stay on the toll roads as much as possible. If you are driving between cities, try to form a caravan with other drivers so you can hide in amongst large trucks.
The stories are probably worse than everyday life but I am told that traveling outside the cartel areas is relatively safe except for the cops demanding bribes.
