Carrying a weapon opens up a plethora of legal problems and ramifications above and beyond the inherent dearth of skills that the "just carry a weapon" crowd possess (or rather DON'T possess)
TS, Wing Chun is bullshit and everyone here can tell you so. If these schools don't spar don't bother.
Go to a boxing, MMA, or judo/BJJ place. I guarantee that after 6 months in an MMA/Boxing/BJJ/judo gym, you'd beat the chun sifus, their students, and any potential mugger into oblivion
If you want something practical, pick something that is proven to work every couple weeks in front of millions of people instead of what you're told that works but looks like silly slap fighting any time you see a video of it on YouTube.
Or look me up - I teach in Calgary Monday and Friday evenings
If I were going to a new area and looking for a school my first instinct would be to find the school that local military and law enforcement people frequenent. If a group of people have a job that requires them to be prepared for violence on a daily basis trust their lives to what is taught there you are probably on the right track.
Keep in mind this doesn't count desk bound cops who have a belly that hangs over their TKD black belt :)
And yes as many have said if they don't spar frequently you are not learning to fight.
In answer to the thread-title question:
For your sake, OP, I hope to Hel it isn't.
I love working on wing chun and have recently made my own mook jong.
