Quick question (re. the show that we are planning for next year)

Anybody know the legal/planning situation regarding a car meet/show held on private farm land?

I am 99.9% certain that its classed as temporary use (as indeed it is) and therefore needs no permission

I don't want to ask the council directly, as that simply creates problems where none existed!

I understand that I will need insurance to protect myself/my company, as organisers, but this is pretty cheap and not an issue.

I believe farm land may be used for 28 days a year for "temporary use" several airstrips have been setup & used on exactly that basis & boot sales work on the same principle, so can't see why you should have any problems other than requiring insurance to protect yourselves.
If it's going to be a large gathering &/or there are any access issues that might impinge on local road access/parking etc. then it would be a good idea to inform the local BIB just so they are aware it's a legitimate gathering.
