Garden hopping to some. Had a Grand National which lasted over a mile and took retribution on posh kids in big detatched houses. Climbing each fence and hedge was exhausting especially with grown men occassionally in pursuit. Always liked the water hazzards as difficult to see them on other side of fence. Mate broke his leg when he fell into one and, unlike war films, we did leave him, it was better that way. There was also a flat course called the Derby over rows of terraced housing back yards that a competing school used but clearly missed the point of both amusement and class action.
