Being without broadband internet over the past few days during Verified Voting Lobby Days was tough. Really tough. Especially when Representative's staffers would ask you questions that you knew you could answer definitively, if you could only surf around a bit.
One day too late to help, The Open Park Project announces free WiFi on the National Mall, right between the Senate and House office buildings. Which means there was probably a signal there in the few days prior, when I could have used it. If I'd only known!
