Because the thieving barstewards can see what you've got as most people use their best tack at shows,( and who doesn't leave the horse tied up and tacked up in or beside their wagon?) and then simply follow you home. Unfortunately it is a bit like inviting burglars to an open day in your house but I can't see any way of preventing it. You are the third person in Cheshire who I know personally was robbed immediately after a show - one lost his brand new HGV wagon.
Bloody hell, never thought of that! However my best saddle and one id used at show was in the tack locker as never got back from show till 7.30pm at night. But thats all i have left, one saddle and bridle for 3 horses. Where abouts in Cheshire are you?
