I've mentioned the Degree Confluence project in the past (www.confluence.org), because I've been out there zeroing out my GPS unit: twice to 30N 90W, one trek in the middle of Lake Tahoe and others. It's great fun! I was introduced to this project by Dr. Joseph Kerski. Appropriately, The American Surveyor has featured a beautiful article on his journeys to "feel centered." http://www.amerisurv.com/PDF/TheAmericanSurveyor_Kerski-PointedJourneys_Vol7No2.pdf
