Don't get my town's Facebook group involved in this question. Most people: Eeewwww! Dog owners: I pick up after my dog, horse riders should also use poo bags! Gardeners: Where is it? I'll bring my wheelbarrow.
If you're in my area, apparently just leave it there. I used to bike to work and had to slalom around mounds of horse crap. Apparently people just expect the wind/rain to take care of things...
No idea, but if there is someone getting paid solely to do that job, there certainly isn't an industry behind it like before. One of the fears growing from around that time was that so many would lose their jobs due to the advancement in technology. It's a reoccurring rhetoric as tech advances more and more.
