About 26 maps....so if you charged $5.00 per map, that's roughly $130. Pretty good salary for a day's work, especially with the entertainment factor you would get as I try to find these "1 cache on a map" caches.
So it would be east to St. Croix, North to Fort Kent, west to Rangeley, and a big paddle to Vinalhaven.
We haven't left yet? LOL
In all seriousness, I estimate it will take me all summer to finish this and at least 5 separate trips.
