Bane and Gilbert and the now-ignored park plan were correct .  I see here a NPS drift toward amusement park aspirations and that is a very very wrong direction.  Nothing much in this for the bears.  As MacIntosh points out, a photo in Banes book shows a sow with cub on her back trying to find her way through solid line of  tethered float planes along a shore in Katmai. This is symbolic of the trashy approach the NPS has taken to fulfilling its mandate.
The great NPS budget shortfall should prevail if it helps put a halt to amusement park NPS  designs. Here they've cast aside their own planning document. When Bane objected  to NPS he was told to get lost. 
This Nasty Park Service behavior is unacceptable. When NPS was asked to aggressively defend and advocate  its wildlife such as Denali NP wolves getting trapped and shot in an area that should be protected but left outside of park bounds, the response? It's not in our authority, and entire packs disappear. Shame on NPS!
