Cache is located at Jeanne Rosset French Memorial Park in Skippack Township. Park is site of a baseball field, so at times there may be a lot of activity there. If so, it might be better if you just drove away and come back another day or time for this one. It is almost a park and grab... except for short walk where you may encounter poison ivy, thorns, and of course the ubiquitous ticks.
Township rules are that parks are open from sunup to sundown. Coordinates for parking are for entry to drive into park.
