19 : my posse steps off
We're in line and marching now!
Except there are so many thousands of people marching that we're more shuffling and strolling.
We're actually in a column of people that formed on the Mall to join the March proper. In a few minutes, we and everyone in front of and behind will all have to step over a fence. In our excitement, we've lined up on the wrong side. Oops.
