I went to Manchester and Leeds Bradford yes, (The latter as A. it's local to me and B. I figured it would be interesting to get an alternative insight to NATS). This was back in February 2014 just after I passed Stage 2 though.
Somebody on the forum has kindly given me an email for Claire Burton at NATS whom I believe I remember from my Stage 2 so I've sent her a message asking for some assistance so we'll see if something gets sorted that way.
I'm really only going to be available on April 2nd for the forseeable future due to work commitments and I'm going to be around that part of the country then as well so it only makes sense to try and poke my head around whilst I can!
