I have an interesting situation and I am wondering if I can trap just
this specific error...

undefined method `[]' for nil:NilClass

which comes the user is trying to access a controller method which
assumes session variables that no longer exist because the session has
timed out.

I would rather bounce them to a static web page than toss the
application error in this case. Is this possible?

   #access the session that errors out
   redirect_to '/somewheresafe'

Or test it using nil? before calling [] on it...
