Bitter sweet accomplishments today. It was a dream of my dad's to have a place where he could easily and openly communicate with his customers (Land Surveyors) and help professionals solve problems from the field. In March of 2007, I began building Land Surveyors United Community during a time when Myspace was still the primary social network. Every single day since then, I scroll through applications to join at least 3 times a day and decline most due to lack of seriousness in the answers they
