We've actually lost a cache while caching, we'd taken the cache into the car to sign the log & take a photo as it was so titchy & fiddly, we were about to return it to it's hide when Z my son dropped it still in the car, we moved seats back & forth, looked in all nooks & crannies, posted a log & an apology on the iPhone, gave up looking, stopped at a nearby house to see if we could borrow a torch which didn't help only to literally pull up at home on the drive & Z saw it lodged in the seat framework, we didn't even get out of the car just returned straight away..what made it worse was the it was a FTF which could easily have been Last to find as well
