The entrance to the McKinley track.
Notice that this track is only 3-sided. The kids run on the blacktop and hop back on the track when they enter the grass area. It works for us.
It's a perfect 1/5 mile loop, about twice as wide as our other 2 paths, and is perfecctly flat. Spectacular!!
Their border is concrete on both edges and the track is, again, filled with decomposed granite.
