Harry S Moss Park

Hall-O-ween with Harry!

Hall-O-ween with Harry! 

Sat., Oct. 15, 2022
Harry S. Moss Park, Dallas

The second orienteering event of our season brings us back to old haunts! Harry S .Moss Park has been one of our most popular venues for many years.  It’s gone through many changes over the last few years due to flooding and severe storm damage. New infrastructure is coming in. But it’s still a patch of wilderness in the city with twisty bike trails and low-lying forest. Every October, some some strange new features appear… What will we find lurking in these woods this time? That’s for you to discover!
