Do they still tell people on small patrols to collect their shit in clingfilm to avoid "leaving sign"? I mean, what a load of shit i) Any dog is going to find a load of it up in the air a damn sight easier to track than buried, and buried tells them where you were, not where you are. ii) My pal was relating an attempt to make the cling film thing work lying on his side with a stomach upset. Not hygienic (although funny for the uninvolved). Whatever theoretical advantage there might be is surely outweighed by the health implications. It's just occurred to me - is the whole "collect your doings" a massive wind-up?
