In l966, newly returned from living in Tanzania, I ordered a wig (very fashionable at the time). it didn't fit, so I jumped in the car, drove from West Kingsdown to Rochester, looking for P.O.Box 115!! Yes, I know, stupid, but ignorant was my middle name! I arrived in Rochester at a T-junction with a huge dark brick wall facing, no signs of any description to be seen, and decided to turn right. Between the first two buildings was a large entrance with a man standing on the pavement.
