The story here is even worse than it appears at face value. Given the price increase, from $50 to $80, sales completely tanked! Doing some very rough math, NPS sold approximately 440,000 National Park Passes in 2006 (which by the way isn't an anomaly, its in line with the steady increase in sales since the launch of the NPP in 2000). But that same rough math reveals that NPS sold approximately 260,000 of the ATB passes. The price increase masks the dramatic drop in sales! This isn't the fault of the NPS Fee folks by any stretch - the ATB pass was forced on them by Norton and her lobbyist cronies. The Bush/Norton legacy will haunt the national parks for a long time.
