Z , you still have the option to bail at the 1/2 way point ,
its an easy road out from the falls/lake junction - you'd
be home early afternoon like 2 or 3 maybe earlier ...
squared was thinking same I think ... you could hike out together,
its a hard road that runs alongside the river - hard to get lost ...
the falls run is a nice leg of the journey though ... you'll want to do it at
some point ... your rubi is more than upto the task
