Just thought you'd be interested to know that there is a film that has recently been uploaded to YouTube which is supposed to show the actual water tower that was 'Castle Saburac'. Carol and I have left polite and appropriate comments to educate the gentleman who has posted it but thought you might want to check it out yourself.
Yes, I think he is actually at Honeysuckle bottom and that is not Castle Saburac. However, it WAS in that area in the wooded part where they filmed the scene where Sam was dressed up as a Norman and Catweazle dropped Admcos. Thanks for your alert viewing Vince old chum!
