Inconvenient.

But wait! There's an alternative to skinning, butchering and serving
porcupine  for alienating  aggressively intrusive guests.

   + Dress normally but

   + wear a hat, not totally silly like a clown hat or a sombrero but
     anything that pretty well covers your head,  A touque or
     non-meshback cap might work.

   + At the point that you need to mau-mau [1] the target, give
     h{im,er} a conspiratorial wink, briefly raise your cap to show
     that you have a tinfoil wrap underneath, quickly replace cap and
     pretend that never happened.

The potential downside is that your target my think you are yourself
one of the Gnomes of Zurich, the Illuminati etc. and love you for it
rather that forever thereafter avoiding you as an incomprehensibly
disturbed person.

BTW, Bruce, just what is the relationship between mesh and obstructed
wavelength of a Faraday cage?  It's a practical question if you want
to wrap your chipped credit card or passport in screen wire.  What's
the wavelength band for RFID and similar chips? What mesh size(s) will
block it?



ObSmithing:

Attachment of insert to upper A&O die was successful.  All installed
on the tup.  Have to go buy the proper wrench to tighten the
cap screws, tweak the lower die tab a bit, but it looks good.  Pics
taken, URL soon.

    unfamiliar.
