Glad to see you guys had fun (wish I was there).
I didn't go this year for two reasons:
1) I had work commitments that were not possible to change with the client,
2) if I could have changed them, I would have dropped a couple of days work, which makes it a very expensive track day for me (self employed).
Personally I think Cadwell is a cracking track. I would like to do somewhere different such as Donington, but the above shows it wouldn't have changed my ability to attend, regardless of where it was.
Even though I didn't go, a big hats off to those that put the time and effort in to get these things organised.
