The Belgian Raceway

I’ve been clearing out what here has been dubbed the Belgian raceway. The first picture is a before picture and the second picture is an after picture. The dogs would plow through this in the middle of winter but the growth is extremely tenacious and full of roots in the ground. When the plants are broken off they leave sharp spikes sticking up and I always worried about the dogs getting hurt. When I removed everything and prepare the ground I’m gonna drop a bunch of grass seed on this which should prevent any other growth from returning & the Belgian raceway will be fully complete.
