I'm concerned about the safety of the wildlife. They shouldn't allow bikes on the Pogonip. Mountain bikers have a competitive speed-oriented attitude. I'm a former horse patroller at Wilder Ranch and have seen bikers down from speeding. Mountain biking is usually not a nature experience.
Fast bikes are hazardous.
The Pogonip is not that large. There should be a few environments only for hiking. As soon as you say it's OK, you get the hammerheads along with the responsible bikers. The pounders will come through three abreast. The Pogonip is a real gem.
