Don, you've obviously overlooked the disclaimer that I posted during last year's TT.
"Science Note: It will come as a mammoth relief to our readers that, after years of scientific research, I am in a position to confirm that an effective deterrent has been discovered for the ghastly Gorse Lea Midges. Expectations are high that we will be nominated for a Nobel Prize, although the Peace Prize is unequivocally out of the question due to the vocal decibel levels generated by RR Berrie, DSM. On Tuesday evening we successfully repelled the enemy by burning long green herbal incense sticks. It must be emphasised that these are being used for reasons of health and sanity. The Gorse Lea Marshals take no responsibility for the orange-robed, chanting group that have set up their wigwams in Harold’s field."
