Yes litter is a real pain but as my old mum used to say, its not as bad as some of the eyesore permanent buildings that have been put up throughout the UK. Litter can be cleaned up but an eyesore tends to be permanent. I just carry a plastic bag with me and clear up bits and pieces of other people rubbish as I walk, not all of it of course, just the bits that really annoy me personally, usually cartons and food containers thrown out of car windows. As to roaming, I think there is a general intolerance building in society, whether it be about immigration, the underserving poor, people who choose or have to live in caravans, etc which I suspect is fueled by the times we live in, political opportunism to get votes from those who want to think this way anyway and I think generally led by intolerant newspapers like the Daily Mail and others like them. I remember the 60s, for me good times, good times!
