The exact location of the Montana Factory is top secret and Like Airwolf‘s lair, tucked away inside a hollow mountain best reached by helicopter. An Italian man named Angelo arranged to meet me on the helipad of his yacht before we flew out for the guided tour (about half an hour from Barcelona). I was slightly disappointed not to meet any Umpa-Lumpas, though enjoyed a fascinating insight into the process and special formulas of the Spanish spray-bottles. The day conjured up strange feelings of nostalgia – combining memories of a trip to Cadbury’s World as a child and my teenage years spent order-picking in an Argos warehouse. Thank you Montana people. You never got that treatment with Hycote (mind you, we never used to pay for that)!
