We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Jilly
saying something like:

A cable (eg Master Lock 15mm braided steel cable) would be much easier
to use than a chain - but are they any good, or will a serious axe
(against a concrete floor) or hacksaw attack just chop through them?
Has anyone any experience?

Cordless angle-grinder, easy-peasy.
