Narrative:

Received clearance and 'hold for release' prior to taxi. Announced intentions on unicom frequency and taxied to runway 18 pvu. Checklists were completed upon reaching end of runway and departure area clear of traffic so we departed forgetting to get our release. Complying with our expecting clearance, we began a turn to leave the traffic pattern west to ffu via pvu 228 degree radial and 8000 ft. I switched frequencys after announcing intentions on unicom and immediately remembered the 'hold for release.' checking in with salt lake I apologized for departing without release. The controller was forgiving in tone and provided us with our clearance after identing us on radar. We remained VFR until receiving our clearance. Contributing factors: first officer flying and passenger on board. Captain in go-go-go mentality? I usually am PF with passenger on board. An aircraft called (just prior to our takeoff) on downwind, leading us to go now, so we don't wait? Beautiful WX -- completely forgetting about a clearance and no tower to control us.
