I'm going to guess you don't live near SF. And I will bet that if you did, you would have been out there searching, too.

Just in case. That was part of my motivation anyway. Why take the chance that it is there and leave it to someone else, especially if you're close enough to take a look?
Anyway, as for using the GG Bridge, tons of people walk across that thing all the time (generally tourists) so a few more people searching for the phone wouldn't be a big deal...besides, unless they hang that damn thing from the top of one of the cables, there are no hiding places on the bridge itself. At either end of it, though, it's a different story.
And as for letting people find it after a few days...well, it's been going on since June 21, so it's been about 2 weeks which is more than a few days in my book. If there are 17 out there and they start letting us find one or two a day before launch, the excitment and buzz are still out there AND it might even grow becasue people would know what to look for and think they still have a shot.
Bottom line, we got nothing so far, so the hunt continues...
