Wow.. I never felt I was the final word on the subject but, lol I just got my eyes opened! I honestly never suspected so many various fields for surveying. I love diversity within a trade. Good stuff guys... I also like the sense of humbleness I'm reading.. no arguing, just facts offered. Was kinda getting burned out reading everyone trying to outsmart the other. For the most part I like to believe we are all smart men with varying degrees of specialization... strong work boys and good luck to you hunthigh...
