Hi do you mean Leyland show as in Leyland and District Riding club? Coz I know it as Coppull show with it actually being held in Coppull and not Leyland. If so, then it is my local show and is within easy hacking distance from me.
I was a member for years and always had a great day there but due to various reasons I haven't done any shows for about 3 or 4 years, but am hoping to get to some this year- so I might see you there! I dunno if they still have them but they also used to have a practice night once a month on a Thursday night for the jumping which I found really useful too.
