New comic: Fairy tale (Patreon)

Whenever I take my dog for a walk on the trails near our house, I always see at least a few dog poop bags on the side of the trail during our walk. It's problem on nearly every dog-friendly trail we take. 

Apparently people leave them with the intent up picking them up on their way back. I get not wanting to carry it if you're on a long walk. But I'm pretty convinced those who actually do pick it up later are a rare breed. Or do they exist at all?

Is this a problem where you live?
