The 'map your fish' feature shows where the smolt goes between updates, provided it swims enough to generate that data. Flashy from the Skok is now at 130 miles and the map shows him twice swimming up to the Bridge, failing to push through and then retreating back down into the canal. One other fish map (can't remember which one) shows the smolt dipping into a side channel, then it figures out that isn't right, and it heads back out into the main channel. The map doesn't work with Internet Explorer but works fine on an iphone.
