Ouch. Sounds like you've had a particularly bad time - was that in Plymouth specifically or Exeter? I can imagine racial issues being far more serious in the SW given the absolute lack of racial minorities. Luckily I never witnessed it/plus my friends and I were brought up to despise racism. It is more the chav families I think.
And yes, the cavern is nice :)
Anyway I fear we are digressing from the discussion rather here :) email if you fancy, address on profile.
