I know what you are saying Bill, but individual breathalysers are around £5 and I'd prefer to be safe than sorry.
I've not taken the Zed abroad, but have driven both my Triumphs around France, Belgium, Germany, Luxembourg and Holland and in each country driving is a much more pleasurable experience than here. It is how I imagine it was in the UK many years ago. Whilst my wife has come with me on several occasions, she prefers the sun and a beach side holiday, so often my son has been my passenger and we have really enjoyed ourselves (memories that will stay with me forever) so don't be put off if your wives are not too keen.
