At least you know where it is. You have that going for you.
If I did, there would be some major explaining to do, considering the ocean is over 1,000 miles away!
All rivers and streams eventually lead to the ocean (or an endorheic sea).
I suppose it could always have been a fish that ate my phone and swam back to the ocean. hehe
I dropped it once, while boating. However, my phone's a NOKIA, so it tore through the boat and disintegrated any water that tried to get it wet. Luckily, I managed to grab it before it ripped a hole in the Earth's core.
