Frank,
I have considered that and a Balaclava for the Tax Camera's (Who was driving), the only problem is, the cowboy hat would keep banging on the roof and the headrest and the Balaclava as it covers your mouth, would be a right pain in the you know what, when trying to hit my mouth with the old stogie. If I had the window down aswell, it could lift the front of the stetson up on my head and I could look like a cow-girl. So I have decided to keep the window shut, by a balaclava and cut out a hole for the mouth and get a pair of mirrored sunglasses, I think that should do it. I might just get Lady Stig to darn me some wording on the front of the balaclava across the forehead area, just so the Tax Camera's have something to read..SUGGESTIONS PLEASE...!!!
Cheers
R
