100 Ton's per year !?! ; far out ; looks like IBM itself is exempt !
"Small guys" processing less than 100 000 kg's (are we on metric tone ? ;

Well , have to admit, I don't fit to jap cars (height 'm talkin bout here,
ok ?) ;
so I'm really trying to comprehend the scope of your "exhaustive" answer ,
if yo' know what I mean .
Somehow my flabbergastation is gettin' worst still !
See you paul
PS
Nothing taken literally buddy ; going to hit the beach at sunset ; to ponder
over life in LA .
Being on top of food chain accumulations 's got lesser risks here by the

apart from steroids from beef and antibiotics disfunctions from poultry .
But : as Patrick said ; fallin' accidentally the Empire Building, passin'
each window :
"So far so good"
