I erred in contacting Cape Approach (while airborne) for a clearance
recently. The controller - correctly - directed me to the CD frequency.
I should have known better.
He was reasonably friendly about it, explaining that he didn't have time
to read a clearance. That was far more than I needed; just the reminder
to contact CD would have been enough.
Where's the error? If you're airborne and requesting a previously filed
popup CD is not the proper frequency to call.
