It's been a year... the organizers of the Women's March will be holding an anniversary "Power to the Polls" event in Las Vegas.

Meanwhile various events are being planned around the country. A search for my ZIP Code brought up marches in DC, Baltimore and Frederick MD, plus other events. You can search you own area here.

I am planning to participate in the DC march, though thanks to the torn ankle tendon I don't think I can do nearly as much walking this year as last. So I'm not sure how involved I will be able to be.
