Up the Boott Spur Trail, great option to get amazing views down into Tuckermans and Huntington Ravines if you have the weather. The longest route distance wise but I think the best for views and pleasure.
"So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life."
