Maine - Rough Guides Professional Review and Guide
"As big as the other five New England states combined, Maine barely has the population of tiny Rhode Island. In theory, therefore, there’s plenty of room for its massive summer influx of visitors; in reality, the majority of these make for the southern stretches of the extravagantly corrugated coast. You only really begin to appreciate the size and space of the state further north, or inland, where vast tracts of mountainous forest are dotted with lakes, and barely pierced by roads – more like the Alaskan interior than the RV-cluttered roads of the Vermont and New Hampshire mountains, and ideal territory for hiking and canoeing (and moose spotting).
The vast majority of visitors to Maine drive.The most enjoyable route to follow is US-1, which runs within a few miles of the coast all the way to Canada, with innumerable turnoffs to hidden seaside villages. In the interior, the roads are quiet and the views spectacular; many belong to the lumber companies, who keep careful track of who you are and where you’re going (and charge you for the privilege)."
