The first of the two Cars in the Park Events is at Newby Hall on 13th May.
Newby is located between Boroughbridge and Ripon, so in the wilds of North Yorkshire, but its an easy find from the A1. I went last year, and it was a really good day out - the kids had a great time in the grounds of the hall. The organisers say that its also the day of a flower show this time, if that floats your boat.

I think you can just roll up, but you may not get to park with the rest of the cars, and you would have to pay the full admission regardless of your interest or otherwise in the hall.
I've bought my ticket already.
