Over the past week, several dozen crows have been gathering at the Governor's Mansion in central Denver at dusk, though I haven't confirmed that they roost there overnight. A small number -- fewer than a dozen -- hang around the adjacent Governor's Park during the day. On blustery afternoons, a dozen or so of them will often gather on one of the large apartment buildings east of Governor's and then launch themselves into the wind.
-- Close to 100 often gather at Cheesman Park in the cold months. Now and then, they decide to close out the day by showing off for each other -- flying, tumbling, calling wildly -- which is a pretty spectacular event to observe as the sun sets over the mountains. Even better is when they decide, also at dusk, to mob the resident Red-tailed Hawk as it flies over the park. Even my dog stops, cranes his neck, and takes that in.
It wasn't always like this in my neighborhood. W.H. Bergtold, a physician and ornithologist who lived near Cheesman Park in the early-1900s, reported one crow "flying over Eleventh Avenue, and Corona Street" on December 7, 1913 and another one "seen in Cheesman Park, May 1, 1917."

Hi COBirders,
Just adding to the thread …
When I taught at Air Academy HS I used to regularly see large flights of crows leaving the canyons on the West side of the Academy, heading towards town. Usually this was early morning, in the winter months. Never saw a roost, but hundreds of crows would fly over some mornings.
