I feel sure there must be decent individuals in the traveller community, but as a group they are a pain. They have no interest in any particular location, no loyalty to it ir the local residents: so give next to nothing to it, but need to stop so have a, "You must provide for us", perspective. And no incentive, aside from personal moral values, to treat the place decently. If they must travel why don't they all opt to stop in the wilds, and clear up after themselves ? Leave residential areas to the residents who contribute.
