It is the laying of a 'scent' for dogs and riders to follow rather than chasing a fox.
Oh, it's drag hunting. Not sure why the old established terminology has to be changed. Drag hunting isn't illegal.
Right from the start of the anti blood sports movement I've felt that it is in part motivated by an 'anti toffs' feeling.
There were probably thousands more innocent bunnies slaughtered each year (and continue to be so) by 'lampers' with dogs, but they operate in the dark, at night, and aren't high profile at all... They're not very well off, either...
Does anyone have strong feelings about saving the bunnies, or is it just foxes that get all the love?
