Lee, That is very interesting and by far the most detailed I have seen from an on-line source.

I must admit, I am a little spoiled in regards to the procurement of my maps. There are several Forestry service offices in my immediate area, so it' s really just a matter of going down to the office and picking out the quadrangle that I want.

I do however have a question though, when you print out a page of a specific area, does it already have tick marks with Datum?
