If you look over at the sidebar you'll see a new link, DC Happy Hours. It leads to a slapdash map of DC-area bar specials that I threw together today after work.
By clicking on the different days of the week, you can find out where the deals are each night. Click on a flag to find out more about the bar and what they have for sale. (Sorry about the lame Yahoo icons. I'll try to come up with some a little more presentable.)
All the information is drawn from a spreadsheet that made the rounds earlier this summer. When I google around a little, it looks like it might have originated at The Washington Post, but I'm really not sure. So you won't catch me vouching for any of it. As far as I know, it's either out of date or completely false. If that happens to be the case, let me know so I can fix it.
