I did all of that. Back home in Singapore, I'd go to Mt Faber (which is actually just a hill), to have a view of Southern Singapore. While cycling in S. America, we'd always stop to have a drink or just to rest when we come to a section where we could have a view of the town that we're descending into (we even stopped once for a cola to enjoy the view of the canopy of the Amazonas). Many times, the city is in a valley and we'd trek up to one of the surrounding hills to get a view. And, like so many others, we pay to get up to the tallest building in Shanghai. You ascend KL Tower, Macau tower, Umpire State Building, etc etc etc.
But the only time that I got really really really really excited was just a few weeks ago when I went up to the Skybridge @ Pinnacle (Duxton) on the 50th floor. I wasn't just excited, I was exhilarated, adrenalized! I swear I had this stupid smile on my face all the time. It's simply amazing! I never knew that my city, this city that I grew up in could be so different from that point of view! And I loved it!
And so, it got me thinking after that. Why do humans enjoying viewing from above that much? What is it that makes it exciting? It's probably a combination of many factors. I was there in the evening, it was dark, the city lit up, the wind was nice and it cools down the perpetually warm city. What more could you ask for?
Let me know if you have have an answer! =)
