N-a-B,
I do indeed know what training is undertaken at Collingwood. I was a stude there myself last century and have good friends instructing there in light blue at the moment.
As to the housing development thing... It's the same for Arborfield and Bordon. Both are earmarked to become very large housing developments. (when the quarters are eventually handed back from being overspill for Aldershot with the returning of the last gaspers of BAOR.)
