You went to a field next door to a sewage farm and you could smell sewage???? How bizarre!!
You have heard? From whom, dare I ask? The voices in your head?
Of course it's bloody safe! The fool who keeps posting the made-up scare stories on here and then attempts to add weight and credence to them by replying to himself, doesn't even live in Dawlish any more. That's why he keeps posting anti-Dawlish messages on here. Ignore the poor old sad and lonely man and carry on enjoying your life. Remember that it's not a rehearsal.
