Winchester Treasure Hunt followed by Social and Buffet

I’m looking for Expressions of Interest at this stage.

Thought you knew all there is to know about Winchester ?
This Treasure Hunt will take you to parts of Winchester you might not know existed.
This is a walking Treasure Hunt/ quiz in and around the city, will start at 14:00 and finish at 17:00.
The Buffet and Prize giving will take place at a secret location (worked out or disclosed on the day) from 17:15.
I am looking for teams of up to 6 people, friends and prospective new members welcome.
There will be a cost (no more than £20:00 per head to cover the buffet and prizes.
