Well any NW DSC member could tell you that, myself and Lily pretty much head off into N. Wales most weekends, only takes 30 minutes to hit the first of the twisties from home
Weather is an issue though, but that's the same as anywhere in the UK (thus maybe the foreign tour appears better???)
I think there might be a plan for a NW Mega meet next year for a weekend which could involve a trip to Wales, but there's always RTL '06 which has equally impressive roads
