There's a drainage area being built on the corner here, right now it's a few feet deep and dirt. My son and I were playing in it today with his trucks and he stepped into a pile of leaves and disappeared into a drainage pipe. I had to put my arm up to my shoulder in the pipe and was able to grab him and pull him out. I've never been so scared in my life. I had the firemen across the street stick some cones in the drainage pipes, all of which were hidden by leaves.
This is a serious danger to any kids in the area and even smaller dogs. They need proper caps on the drainage pipes like the finished ones on the other side of the park or something.
