Definately keep a copy of that PP - and keep it somewhere with U - but not on UR person. With that copy and in case of theft, it can often be replaced by the consulate "on the spot."
Without the copy, and if you don't know the PP number, a "time consuming" wire will have to be sent back to the States to locate the number. At a minimum, take a look at UR PP and note where it was issued (LA,HOU,WAS, etc). This will help the consulate direct the wire to the appropriate location, if U have this information - as consulates don't seem to have a centralized computer with all
PP numbers, etc.
I learned all of this last year after an encounter w/ a thief and his machete in Santo Domingo, Dom. Rep.
Nothin' more than food for thought - just in case...
