Trailers Any Shoulder Wheel Thru as Leaders 3/4 Out.
A Mini-Wave Box ends in a Mini-Wave Box.
Notes:
- 
A 3/4 Out is a 1/4 Out & Roll & Roll.
 - 
From a L-H Mini-Wave Box, Trailers pass Left shoulders.
 - 
Trailers often clap hands as in 
    Wheel Thru [A1].
 - 
Some dancers cheat the Leaders part by doing a 1/4 In.  This
    can get you into trouble if the caller adds a Roll, calls
    1/2 Bingo, or uses a concept such as 1/4 Stable or
    1/2 Stable.
