Even in the 70s,the Crimson Crabs were not allowed to be housed with the rest of us.They got zapped too often!!The Boss used to send recce parties to find their Hotac.Usually identified by Red MGBs or next year Red Hondas,as I remember.Our Greenie did a splendid job of placing herrings in the Heater boxes,and potatoes up the Hondas Exhausts,at a particular establishment one year to then again find them at another the following year,whilst at Greenham IAT,similarly at the Bournmouth Air Pageants,when they were moved from the Dormey to a secret Hotel,which was duly discovered.We then made it SOP for a Crab Hunt wherever else we met them,and that carried on into the 90s,so hardly surprising they still stay elsewhere??.Such merriment was had in those days,which would never be !!!!!today.
