Pinfinder, Survey, or...?

[maud gonne]

This is good information and I thank you all. We've actually verified the pins themselves - right where the stakes are. But I'm wondering about the 150 ft or so between the pins/stakes. Do people run colored tape, or how does the dozer operator actually keep to the line? I definitely will contact the county first - thanks for that tip. And we will be using a "conscious" dozer firm - we want minimal impact on the flora.
