The other day I wanted to get a clearance to get above an overcast
while in cruise. When I asked for a clearance the controller said it
would be awhile because my destination was more than 500 miles away.
He said he needed to get me a clearance all the way there even though
my intention was to cancel on top. The controller than mentioned that
he could issue me a clearance to VFR-on-top w/o the entire route
clearance. I did that and it worked perfectly. I learned something.
