Walked it with my son from the bridge below the dam back around the soccer fields to the road.  We picked up the medium stuff that could get stuck in derailleurs or kicked up by wheels.  Left the small stuff (and there was a lot!)  No big stuff to worry about on that section.  The banks of the creek right under the bridge are pretty eroded but the bridge is still stable.  Someone with more engineering expertise should take a look at it though.  The 6 foot approach bridge got washed up onto a rock and is very tippy.  It needs to be reset before someone tries to ride on it.  Sorry we couldn't check the whole trail but my 9 year old was getting a little grumpy after an hour.
