There is nothing that makes me more mad than someone who lets their dog crap in my yard, but then again, I have never had a human poop in my yard, so that could take the cake.
There seems to be someone who actually does this in Colorado Springs. She has been dubbed the "Mad Pooper," and has been pooping randomly in the neighborhood near Briargate and Union boulevards.
The lady, who is usually jogging, seems to take random dump on someone's yard at least once a week, and has been doing so for about seven weeks.
If you know who she is, call the Colorado Springs Police Department at 719-444-7240.
