You don't have to be saying something that is incorrect to sound sour.
Of course some of the SEN Summer 2012 routes will be reduced in frequency or dropped for Winter 2012/13. Indeed it is so obvious that it hardly merits a mention in the context of a new route announcement.
In January 2011 that same poster said of SEN: ".....unfortunately I think you are going to have great facilities but very few people to use them." It doesn't look that way now does it?
There's nothing wrong with negativity when it's based on fact, rather than wishful thinking.
