Didn't there used to be a Yahoo Group set up for people to share lifts to shows? I'm sure I read about it in Dog World and I'm fairly certain it's been mentioned on here before. Hopefully someone else might remember or be able to provide a link, sorry not to be of more help :)
Bugger, thats right on my doorstep... I wish I could but unfortunately not going this year, just come out of hospital after spinal surgery... Sorry, couldn't be much more help.... but you can always pop in for a cup of tea if your lift lets you down ;-)
