You are allowed to run as a guest in the Mid Lancs or Red Rose which you may find easier to get to.
You have to be EA affiliated and a club member that's all.
So for the Mid Lancs, you just turn up and pay on the day and run 1st Claim New Marske and they mark you as a non-counter.
Particularly the ones after Xmas in teh Mid Lancs might interest you with Burnley, Lancaster and Ulverston.
With the Red Rose I think you can enter online in advance. Not sure if you can enter on day. I think you can.
