The cache is located in Delaware City Community Park that is the site of a historic school house (see historical marker)
You will take a walk behind the old school house on a nice mowed lawn as you head toward Dragon Run and its tidal marshes. Beyond the electric wire fence on your right there is good chance of seeing some friendly horses/ponys. Its very short walk--go too far and you are in the marsh.
What is that strange concrete structure? Look inside, but no need to actually go inside to get the cache
