Not been back to Colt since I (thankfully) left after a short tour in 2003, the JRs accomodation* was awful but I thought most of the accommodation had been used for the prison?
Don't know why people get all misty eyed over Colt, when I arrived there in 2002 it was like stepping back in time 20 years.
*Even compared to Odiham and Lyneham which were well known for the state of its JRs accommodation.
