The problem up here is that the going is not the same as Kent, especially if you go the Lincoln's quarry as it;s all big rocks.
I would suggest the Pegasus club which is 30mins down the A1 or the Banovallum which runs trials near Cadwell Park, other than that you have Sheffield & Hallamshire (heard a rumour they have lost Eadons Fields, hope not as it's a crackeing trial).
