illegal exercise

i went a walk by the local river today and it reminded me of some of my exploits from the past which i intend to recreate again soon. one side of the river for a good mile between two bridges consists of a popular walkway/cycleway, and here one can find many people going about their recreation. but on the other side of the river can be found a large row of huge private houses with their gardens steeply and massively heading down to the muddy riverbanks. i used to take my own path through the muddy and overgrown parts of these gardens from one bridge to the next. This is great exercise as each garden has either a fence or a wall or hedge seperating it from the next, and many parts it is a mad scramble across precipitous mud banks grabbing on to overhanging trees for support. so you are dealing with barbed wire, brick walls, hedges, wooden fences, slippery banks, brambles and undergrowths, and the exciting bit, it is trespassing as well. now, the householders, by and large dont bother with these muddy outposts to their steep gardens so it is a fairly unchallenged route, but it is a surefire way to fitness and agility. forget the gym,this is the real thing....illegal exercise out in the open, one slip and you are in the river, evry twist and turn banged and battered by the undergrowth, but get to the other end and you feel great, as you look back , and know you have won the day!
