DC's a bit of a ghost-town right now, I know that lots of people are on vacation, but beyond that there's a significant majority that's choosing to be outside as little as possible. It is pretty damn hot, and will likely continue to be so. I can't say always I enjoy it, but I don't feel entitled to complain, either - the weather does what it does. I haven't turned on my air-conditioning yet, but am grateful for my fans and that I live in an apartment building built in the 1950s and designed to stay cool.
And granted, I'm privileged enough to get to choose to work outside, when many people have to work outside, but I figured this would be a good time to share tips and tactics on how to get by, working in the heat.
