When doing calls within Blocks, traffic patterns vary. For simple calls that
do not require interaction with more than one other dancer at a time, execute
each part of the call within the footprints of your individual Block (e.g.,
Square Thru, Touch 1/4). On more complicated calls (e.g., In Your Block Square Chain Thru),
start the execution of the call to the footprints of your individual Block, and when it becomes
necessary to interact with more than one dancer at a time, the dancers closest
to the center of the set should cross the center line to join the other dancers
in their Block to complete the call on
each side. Once the call is completed, re-establish the Block
footprints by having the appropriate dancers move to re-create the original
slant of the diagonal (i.e., NW-SE or SW-NE) and the other dancers move to
appropriate Block footprints. Note: Some dancers need not move at all to
re-establish footprints (typically, only four or six dancers need to move)!
