Interesting post and have to agree with the NPS notice too. As a previous dog owner I too get it , whether a recreational area, park or battlefield site, we make a mess we clean it up ! Not necessarily a widely held or indeed popular view but the fact remains. Everywhere here is littered with notices to 'bin the poo', parks, recreation areas, suburban streets etc and attracting severe fines for non compliance and indeed, for my 'two cents worth' as it should be.
Btw, the ones who will complain the most are those who would not even consider cleaning up anyway
