With disasterous results, Boston has the crazy policy
of allowing traffic to drive on the shoulders of the freeway,
the area normally reserved for emergencies and breakdowns.

(Note: Massachusetts State "Route 128" is no longer actually that; it is the
local parlance for the Federal Interstate and Defense Highway 95. Be very
aware of this when you drive in a certain State, which has received Billions
in Federal Highway Dollars, called Massachusetts or you may end up like Mr.
Salcedo. These lanes are not marked with any special paint such as Diamonds,
and the signs which list the "open hours" are small and often damaged or
missing. So much for "National Standards"; Highway Engineers: Please don't
"add capacity" to your highways like this.)
