GPS

So, I'm planning a trip on the Trans-Siberian railway for my eventual return to Canada and I was hoping to bring a GPS receiver along; it would let me track my position, tie my photos to those positions, help me get around, and maybe do some Geocaching. As it turns out, GPSs in Russia are kind of tricky. I discovered a post on a forum and when I did some searching, I found that "Foreigners have faced charges of espionage for possessing improperly certified GPS devices". The U.S. page cites penalties of 10-20 years in prison, yikes! Needless to say, I'm going to look more into what's required to legally carry a GPS on my trip.
