Sorry for the lame-o title...

I found this cool website that gives distances between cities &/or points in distances "as the crow flies:
How Far Is It? by Indo.com, Discount Bali Hotels (http://www.indo.com/distance/)

... so I know it's 2734 miles (4400 km) from Miami, FL to Seattle, WA in a straight line.

Now what I want do do is find the nearest city to various distances on that straight line.

For example, what's the nearest city to the point on the line 660 miles from Miami?

Does anyone know of a website or utility that will help me do this?

Thanks!

This site has major cities and you can get distances to other major cities

Travel Distances Between Major US Cities (http://www.travelnotes.org/NorthAmerica/distances.htm)

I found something. MS Streets & Trips has a neato measuring tool that will work wonderfully.
