and through next week into the following weekend.

Stay away! Really do NOT consider attempting to travel on the A354 between Blandford and Salisbury. Ditto the A350 between Blandford and Shaftesbury. It's the Great Dorset Steamfair and from this afternoon onwards those roads will be at a standstill as fairground ride, hotdog stands, beer tents, steam engines, transporters, historic military vehicles and the like all try and shoehorn their way into the showground at Tarrant Hinton. From Monday this will be exacerbated by daily traders and the public turning up and departing. Next Saturday and Sunday will be the worst, but add at least 2 hours to any journey that requires you to use these roads for the next week.

Eh? It doesn't start until Wednesday the 31st, so how will the public be turning up from Monday?

Tell me about it. I made that mistake coming back from Bournemouth last year on a Sunday and getting held up trying to get through Salisbury.

Most of the exhibits will be on site by Monday evening. With them come the traders that sell not only to the public but to the exhibitors. Most exhibitors have local friends who get in on exhibitor passes for the day, either for a pre-show mooch around or to help with setup. Trust me, it's bad.
