I too was a frequent visitor to Horsendon Hill, flew kites, walked the dog, explored and always intrigued with the lore of Hengist and Horsa from a 12-13yr. old's mind.
Spent many visits in the early '50s, eating winkles in the parking lot of the Ballot Box Pub, whilst my parents went in for a brew. Currently living in one of the 'colonies' ('50s), but still have fond memories of 'home'.
