Well, I've got two off the cuff responses:
Bryson is a dreadful narrator; he is most assuredly
not an exception to the rule that authors should write and leave the narration to the pros.
Uh, it's not as if there were no recording facilities in the entire state of New Hampshire. Bryson lived in Hanover. You can walk across the state line (on a bridge) to Vermont from Hanover; it's on the border. The article makes it sound like an overland journey, up hill and down dale, to get to Vermont from Bryson's location, when it fact it was just that the Vermont facility was closest. New England states are small! I can take in three just doing my errands.
