come to think of it.
A couple of years ago I went on a School trip to Thorpe Park , to make it 'Educational' , I had a maths seminar there but all it was , was a guy talking about risk factors of things going wrong and the costs of SAW.He mentioned something about a height limit that would expire some time.I think he said 2013 but I'm not sure (Don't take my word on that).I think Jason may be right.
