Yes, I've had the messages (& e-mails now!) too, and am quite frankly getting fed up of it!
While I'm sure there's been some basis of truth to the tale - there seems to have been some info on the horsewatch website, it now seems to have been blown out of all proportion, and nothing short of scaremongering, something in between "chinese whispers" and a chain letter. This is causing unnecessary panic and distress to some horse owners. So far all I've heard when I've tried to find out the origins of the version that I've received are tales of people who know people who know someone who saw something or might have had something stolen - well, that's practically conclusive then, isn't it?!?
I think it's wise for horse owners to be vigilent, report anything suspiscious and take reasonable security precautions, but isn't this what most of us do anyway?
The sad fact is that horses, horse vehicles and equipment ARE stolen on a fairly frequent basis, and unfortunately this will continue to be the case, as no number of text messages or security measures will stop the most determined thieves.
I'm hoping now that the people who insist on repeatedly forwarding these text messages are running out of credit!
