Jammerfind

I live in New York. My grandmother lives in Vancover Canada. I'm going to visit her but I also want to do some geocaching too. I tried the search but I wasnt sure exactly where the geocaches are. >Tips? >Suggestions? Please help.

The cache might be under water, but it could be attached to a rope attached to something that floats. That way non-divers could swim to it and pull it up. Just an idea.
