every day or 2 in the summer. whever possable in the winter. I womnt go outside when its 40 below to poop scoop lol, but we get random warm days throughout the winter where things will start to melt for a day..those day I will go out and pick up what I can..the next day its usually 40 below and snowing again lol. its finally springtime and the snow is melting so we have been out every other day or so picking up what we can get at. there IS a $500 fine for not cleaning your yard here, so we try to clean up whatever is visable.
