The sign for "Denver" is
done by holding a "D hand" in front of you and moving it down, then
up, and then back down again using a quick double movement. Some
people start further to their left and move the hand sideways toward
their right as they move the hand down, up, and back down again as
if showing the skyline of a mountain range.
DENVER:
(Model: Byron Cantrell)
Dr. Bill's notes: In the video Byron
does the movement multiple times as a way of making clear that the
movement is up and down. In everyday signing at high speed,
embedded in a sentence the sign DENVER is likely to use only a
double downward movement: down, up, down.
