A suggestion for the next edition of the C-1&2 Ceder Chest, please include 
diagrams for Interlocked Exchange the Diamonds (or is the correct parsing 
Exchange the Interlocked Diamonds? - Bill A.'s program prefers the latter). 
Apparently Rich Silkett called a couple of weeks ago and much discussion 
about the traffic pattern ensued. 
Bill's program moves the dancers per the rule, i.e. circulate around the 
outside of the new diamond you are exchanging to. 
Also, suggestions on traffic flow would be good. Normally, I tell people to 
let the centers out first and then the ends go, but in this instance it 
almost makes sense to let the trailing point interlocked diamond circ first 
and then the center circulate out. Regardless of who goes first this call 
results in a lot of "yielding" in order to avoid fender benders.
