Let's talk about blinkers..
I was in another thread here where blinkers were being hotly discussed. I was surprised to see pretty much everyone strongly advising against ever going without blinkers. I think this is probably worthy of a separate thread!
My personal standpoint - I've worked in harness racing stables from a young age, and exercised a lot of racehorses in my life. I've never ever driven in blinkers, and I've never actually had a driving accident either. To me this issue seems to stand out as a cultural issue: Over there in the States (I live in Europe) all horses are driven in blinkers, are used to it, and going without could be dangerous. Over here, you never see blinker bridles, they're regarded as antiques. I've considered buying harnesses on eBay, but felt kind of bad because the bridles that follow are blinker bridles and I just see no need for them at all.
Here is a picture of my horse winning at Momarken Raceway, in 2008. It shows "modern" blinkers which are often in use in races. Apart from that I've never seen him in blinkers at all.
Go debate! I'd love to hear some input. Do you people find it's an acclimatisation issue or not?
