Mountain bikers probably get injured more than hikers with their pedal speed ..... plus biking and hiking along side one another on the same narrow trail is problematic.
Oh well, is not too difficult here in central NH to find a decent pair of hiking shoes/boots down at the local thrift store for short money, and go walk those mountain trails, from end to end, up and down, back and forth, hither and thither, to the summit by the direct route ..... asap-pdq .... in those super high quality thrift store Merrell walk'n shoes ...... and thrift store Thorlo socks ...... and a thrift store Kelty pack with a home made sternum strap ...... just like Pocahontas and John Muir walk'n those trails, long ago....... to the summit ...... how much further is it ...... anyway..... and, when do we eat!
