Narrative:

Aircraft was on GA ramp between txwys K and Z. Called for taxi clearance and received: 'taxi runway 30L, hold short of runway 30R at taxiway north.' (no route was specified.) left GA ramp via taxiway K with intention of taking taxiway K to runway 17 to runway 31 to taxiway north. Passing taxiway V on taxiway K, ground control said 'where are you going?' then said he had expected us to use taxiway V and runway 31 to taxiway north. This is the second similar occurrence in 3 weeks. From now on I plan to ask for a taxi route if none is specified in the clearance.
