Jason Grubb of the Leave No Trace Center for Outdoor Ethics joins us for the eighty-sixth edition of the GeoGearHeads. He shared some information about the organization and tips for Geocachers (available in this PDF) along with the GeocachingPolicy.org/ and Tread Lightly sites. Also mentioned was the Geocache Reference Cards they sell.Note: Jason wrote that he misspoke when talking about the amount of material carried out of the Petrified Forest National Park. It should have been "3.4 million pounds," not tons.The live video session from this Google+ Hangout On Air can be found on YouTube.
