If not for the "very quiet" rule at the 73rd floor due to Metro Traffic, I'd probably bring an FM radio on the top of that skyscraper. Sure I could get Vancouver, Victoria and probably a few Portlands on that skyscraper. That's 1000 feet as it is. And my headphones are too dorky and big to take anywhere in public anyways...
You wanna see big and dorky cans? This is my set of Pickering headphones, circa 1973. Wearing these, I look like the unholy offspring of Princess Leia and Yoda. But I don't care what people think of my headphones. And neither should you about yours. When you get the chance, get up there and see what you can get. Cheers!
