Thanks, that helps a lot.  I really didn't understand the difference, but it sounds like there is enough of one for me to consider the Garmin published maps.

This may already be answered somewhere, but I can't find it.  Is there a reason to pay for Garmin's 24k topo map versus just downloading it for free here?  I live in the northeast, and there seems to be a good free 24k map available here.  What advantages are there to buying Garmin's?
