Permission obtained from the pastors of the Family Worship Center, on whose grounds the cache is located. Thank you very much, pastors!
An old topo map (1983) shows this creek as unnamed, but a sign on Sumneytown Pike, just west of Freddy Hill Farm, labels this as Towamencin Creek. Also, a plaque on the bridge, built in 1962, proclaims it to be a branch of Towamencin Creek. The main branch passes under Valley Forge Road just south of Sumneytown Pike, where there's a similar sign. The two branches meet east of Fischer's Park just off of Kriebel Rd.
Currently, geocaches are prohibited on Towamencin township property, but no such restriction exists for private property. There do not appear to be many caches in the township on private property, but hopefully more will be hidden. Perhaps the board members will see all the advantages of geocaching, forget about the one bad experience years ago when authorities responded to a report of a suspicious container, and lift the restriction. Wouldn't it be nice!
An extraction device shouldn't be needed, but it wouldn't hurt to have one with you. Extract the log, but please don't try to extract the container! Also, begin your search from the church parking lot only. Do not even think about parking on Susan Drive. And no night caching. One more thing: This is a Pennsylvania wooded area, so you know to be aware of poison ivy and ticks, right?
And lastly, some fine print (actually, it's normal print, everything else is just bigger): Cache is placed with permission for location and hide style.
