Thanks David, I appreciate the feedback!
 
What does this part of the statement do though?
 
(
   @Region = 'Southwest'
   AND m.Region = 'N/L'
 
Does the @Region = 'Southwest' act like some IF logic?

Keep in mind that when you have an IN clause in your predicate list, it unrolls:

WHERE col IN ('a', 'b', 'c')

is the same as

WHERE (
   col = 'a'
   OR col = 'b'
   OR col = 'c'
)

So, instead of trying to make an IN clause work (which would have been a bit messing
given your requirements) it was easier to consider the exploited view of "IN"
