I can understand that there is a similar benefit to having a single set of ways and using them for multiple routes instead of trying to use new ways to describe something, that said I'm still not sure if this is the best way to describe alcohol free zones if they diverge on a way, for example, only one side of the way is an alcohol free zone. _______________________________________________ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
