Hi Gang,

I guess this falls under the heading of ..."You see I'm really lazy".

How critical is the mistake (which I make often) where I seem to inevitably cross one of the turns under the other?

Of course I usually notice this around midnight, when I can hardly see anymore.
Thanks for your comments
