Personally, I would travel any distance in the UK to attend a Lexus Owners Club meet,-if last Sundays East Midlands ( my first) was anything to go by, I'd take me and my LS anywhere to repeat the experience, a finer bunch of people I never met.
I'd be up for an overnighter, camping sounds good, -as I mentioned on a previous thread, I wouldn't mind taking responsibility for cooking the food,( barbecue ?) It would also give members a better chance to get to know each other, something not achievable on a one-day meet,whatever we decide, count me in.
