Fort Cronkhite Doors by despino sound published on 2012-03-13T01:48:52Z Recorded at Fort Cronkhite north of San Francisco. The doors to the old bunker have recently been sealed off for safety reasons so no door movement could be recorded. In spite of this I grabbed a tire iron and got to improvising latch and impact sounds. Schoeps CMC6/MK41-MK8 MS. Genre Field Recording
