Narrative:

Just starting IFR flight from khef to klyh. Had been handed off from hef tower to iad approach. At 2000 ft, following arsenal 1 departure procedure for runway 16L. Iad approach instructed me to climb to 3000 ft and proceed direct to 'manassas.' as this made no sense, I tried to clarify my clearance, but only managed to make overworked controller angry. Finally, he cleared me to csn VOR. If there is ever another occasion like this, I will simply request 'say again' until controller makes more sense.
