The actual maps have a scale at the bottom of the sheet, so that shouldn't be a problem. Maps on the web can be any scale, of course. The best guide with the Discovery map images is to use the pale blue grid lines as a guide. They are spaced 2 cm. apart on the actual map, and represent a distance of 1 km. on the ground. A mile is very-roughly 1.6 kms., so one square and 6/10 of the next one will be one mile. That should help. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Pete Schermerhorn, in the glorious Berkshire hills of western Massachusetts
