Update

May not have too many more pictures until later, as uploading is glacial in speed. We're cold and tired and a block or so back from the front of the line, but there's nowhere I'd rather be. Just met some more Iowans! People are constantly stepping on each other, elbowing accidentally, and tripping over one another, but I've never heard so many "excuse mes" and "no problems" in a crowd this big. People would have every right to be surly, but are not letting anything dampen their spirits. More later...
