I rode into DC on the CCT this AM on the road bike (slicks). There are
a few frozen sections where the trail is still completely iced over
and extremely bumpy due to all of the foot prints in the once soft,
now frozen slush. These ice sections are mostly before you pass
through the tunnel heading to Georgetown. I was able to ride all the
way in without sliding out on the icy sections, but if you're at all
unsure, it's probably best to walk those sections.
