Last year hey ?
Next year I bet my last pants yo'll tell me last millennium !

And you even quoted without Cajun technical nomenclatures ! Impressive .
Yes the MIL-STD-202 does look promising . With the barometric pressures
(exclusions) variations kept in mind it sounds right .

Anybody tested contacts life to this procedure folks ?

And,  huh.,'m ,  please don't mention the finesse of round forms of beach
pearls here ; when you go for a dip you don't know where to put yo'r eyes ;
just the mention makes the work stay that much harder ; some of the fine
black one's are out of this world !
We do talk pearls here,  make no mistake . If only could I have a string of
them .........; let's be humble ; few's enough ......

Jap pearls ? Yo've been on South East too long buddy ; must have gotten into
yo' !
Way too civilised up there , no flavour ( Empress Maria Theresa [ Habsburgs
- Austria ] sipped them dissolved in vinegar ) .
Hope I didn't confuse you ;
thanks Steve ;

See yo'                                         paul
