So, Ken and my work around might work if I bring a XXX with the  
application and tracks; then delete the old tracks on the GPS unit and  
load the new ones.

I am no expert with GPS, map, compass and orienteering. So the more  
info I have the better I feel but that may be a false feeling. I will  
be as diligent as possible to reduce the "getting lost" situation.

I do have GPS Babel but haven't used it I will also take the advice  
try to reduce the points on the tracks.
