But remember - it is ILLEGAL to TRANSPORT a refilled cyl not
specifically designated as refillable.

This has been beaten to death. TRANSPORT means for a licensed interstate
carrier to take the refilled goods over a state line for pay. Intrastate is
covered by state DOTs. Private citizens are not hassled because there is
very small danger, and when was the last time you saw them stopping traffic
on the Interstate and looking for refilled one pound propane canisters. And
how would one tell they were refilled?

Sheesh.
