It is not unusual to find Public Rights of Way on less-walked hills blocked illegally with barbed wire fences. While these are easily climbed over, the risk of laceration is ever-present. A trip to the Poundland shop today gave me an idea. They were selling long cylindrical closed-cell foam swimming pool toys/floats. These are about 1.5m long and 6cm diameter.
I cut off a length about 50cm long and then cut it in half longitudinally (with a bread knife). Using a piece of duct tape I made a hinge by taping the halves together along just one side. The contraption was finished with two “hook and loop” straps to hold it together in the rucksack.
On finding a blocked PRoW, simply remove the straps, open the tube and place it on the top strand of wire with the barbs in the middle. Fasten it on with the hook and loop straps and hey-presto - you can cross with ease! On crossing, take it off again and it’s ready for next time.
