All good passers are welcome. The map location should be good enough. I know the best way to find it for sure is to take the long way from the Parkway exit road. The road is findable by old and new maps. You have to navigate carefully, but as long as you take the first couple of correct turns, including the one at Munion Field, you will come to it. I remember the first time doing it that way, I was very convinced I was lost, when at last, I came to Martha and Harrisville. I know it's more simple to come from Harrisville to Calico ( it would seem), but try the ride from the other way.
