In the spring of 2007 I was rushed to hospital with heart palpitations and diagnosed with Wolff-Parkinson-White, a condition associated with a risk of sudden death. Thanks to Keyhole heart surgery to remove an electrical short circuit in my heart, I now no longer have the condition.

Here I present my best photograph from each castle I have visited, along with some very brief notes pinched from the guide books, plaques, etc. I'm armed with my Sony DSC-P1 digital camera and the hope for a dry day! Check back often for updates. Beware though, this page uses font embedding and will take a short while to fire up.

A page dedicated to the popular Now That's What I Call Music! compilation series that has been running in the UK since 1983. Because there are many Now collections besides the regular series, please forgive me for the not quite finished state of this page - it's a work in progress!

British Champ Car fans waited patiently for the better part of three days for genuine action at Rockingham Motor Speedway. But they were rewarded by a competitive race with a thrilling finish in CART's UK debut as Gil de Ferran made an outside pass on Kenny Brack on the last corner of the last lap to take the win. It was the defending CART champion's first win of the 2001 season.
