How safe is my Island ?

[NorthernRaider]

Generally the only problem for the Channels is if TSHTF when its full on tourist season, especially if there is a bit of a drought on. Jersey is particularly vulnerable because it has water supply problems most years (parishes too tight to build new reserviors). A guy in St Peterport set up a biodiesel plant in his garage ( about £1500) not so long ago and he is collecting old cooking hotel from hotels and resteraunts to power his Suzuki 2 litre Diesel. So you could probably go the same route as theres no shortages of hotels etc. Sark is probably the most self reliant , but those houses set offshore on rocky outcroppings are the most secure (cept for tsunamis).

Refugees from France and England esp rich ones arriving in their yachts could be a problem, but overall your in a reasonable spot providing you can conceal your family and preps from the authorities and sheeple.

A failsafe bug out boat to get you to Normandy or Dorset may be prudent.
