We spend one day inside the circuit - Ginger Hall, Bungalow and Sulby Church yard (the PO adj to the Church does hot drinks & there are loos behind the church) the other days outside at various locations according to weather forecast what race we are watching etc. Variety is the spice of life.
Did a few years marshalling at a couple of different points - now that does lock you in for the day but boy do you see the racing close up!
