UK billionare mogul Sir Richard Branson opens his private estate to visitors annually, as part of a generous campaign for the British Red Cross.
Mark details an excellent imitation of the scavenger hunt game on the Branson estate this year, with an integrated Harry Potter theme and some surprises along the way.
Wandering around the gardens, I was somewhat taken aback to come across a note which read something like this attached to a tree stump:
We have to figure out how to rescue Hermione, and quick! Meet me at 3 o'clock this afternoon outside Hagrid's House.
A little later on, I came a came across another card, this time featuring a drawing of Potteresque spectacles. Heading over to the stalls, I discovered that this was all part of a Harry Potter-themed treasure hunt. Despite being well above the target age, I promptly paid the entry fee and set off to solve it.
