I agree with most of what has already been said. They skipped HUGE sections though. Didn't mention anything about MD, PA, or NJ, skipped from Harper's Ferry to Bear Mt., flew over the Whites and briefly mentioned Mt. Washington, so they skipped from Bear Mt, overlooked CT, Mass, VT, most of NH except for 5 seconds of Mt. Washington, then went right to Katahdin.
There was definitely too much about ticks, DDT, pollution.. that stuff is important and part of the trail, but they just spent too much time on it.
