I found out about this protest at News4
But there is more about it here.
A D.C. resident started a Facebook group this morning advertising a "a peaceful, safe, law-abiding ride" tomorrow from Dupont Circle to the Post headquarters downtown. Upon arrival, the riders hope to have a conversation with Milloy and his editors about why his column was "dangerous" and should never have been published.
If you're interested in a long lunch break tomorrow, the ride starts at 1 p.m. at the Dupont Circle fountain.
