Visited as geocaching.com's virtual cache GC7B7QM "Get to da Towah - Do it now!!". As the task is basically the same, I'm logging this one now here as well. Figuring out the answer to the question was not easy; even though I took photos of almost everything inside the tower as usual while visiting landmarks like this, it took me several tries before I figured out the correct answer.
Visiting Toronto on a conference trip. After a long, 11-hour trip from Finland, our delegation finally arrived in Toronto. After the dinner I went for a quick evening walk to this virtual and the nearby traditional and letterbox caches (the last of which I couldn't find). So nice to be back in Canada and the first time in Toronto! Thank you for the virtual cache!
