CARIBBEAN CONTRA
By Don Armstrong
Improper Contra; Double Progression; no swing

A1: lines go forwards and back
    do si do neighbour once and a bit 

A2: on sides: single file promenade in direction you are facing
    and promenade back into... 

B1: allemande left neighbour into a full ladies chain 

B2: pass thru (across)  and turn alone
    half promenade with next neighbour

    i.e. after the turn alone men promenade with the lady on their right
