Last night we had kids on the allotment again. A neighbour alerted a
couple of us and the shed owner legged it down to arrive just before
the police.

They'd tried kicking the shed door in and have thrown some stuff
about. Last time they'd thrown some spades around but we found them
all after a couple of days or looking around the edges of the site.

What suggestions for security? Exterior fences aren't high enough for
razor wire ... so I suspect we need some really prickly plants
instead...

Pyracantha, sloes and bullaces - essentially like razor wire but legal.
And it provides something for the birds too.
