Visiting Helsinki for a couple of days, what else would I do than search geocaches?
First I found the "The Incredible Traveling Railway Station" in Pasila, quite a standard implementation. Walk from Pasila to downtown was not a huge success in geocaching sense, but the weather was very nice. First I didn't find "Alppipuisto", then I didn't find "Lintsi" (too many people around), tried "Alppipuisto" again and still didn't find it. I managed to find "Tram 2 and 2V, Linjat", but that was the only one I found on that trip, as I didn't bother too hard with "Valoa sokeille - Ljus åt de blinda", "Ravintola Kaisaniemi, Helsinki" and "Helsinki Railway Station". They were all in places with too many people around.
The next day I returned to Alppipuisto, and found the cache without any trouble. I wonder how I managed to miss it previously.
