The SD card survived flooding with silt and exposure to the weather for 20 months embedded in a gravel driveway. Amazingly, all 2.5 Gb of photos have recently been recovered. Sadly the digital camera did not fare so well. Even more interesting is that the SD card was from by a budget supplier, kudos to Adata!
