zeb,
Is there a local Land Rover club you could join?
Find out to which show they are going and tag along.
The LR community is in part divided by the two publications choosing to have shows the same weekend.
Generally the LR community don't care who runs the show as long as it is well run and serves the needs of the community and LR traders.
No one can truly say which will be better before they happen, so you have to make your own decision, frankly just like the rest of us!
If I go it will be to Billing only for a day, because it is a bit closer, I have been offered a lift and there will be some people I know there.
I don't go to watch the show-ring entertainment, which I find to be pretty anal and full of oversized ego's.
The off-road courses may be fun to watch, however I have never bothered to participate or spectate at those either.
As a newby to Land Rovers I suspect either of the shows will have plenty for you.
John
