Not too tall at the moment, about a foot or so I suppose - just typical uncut field margins. But I find the grass often catches in the legs as I'm lifting the sticks - I have the sticks made using plastic-coated garden canes that MonkeySpanker off this site posted instructions for. And in order to turn them, I have to lift them high up, clear of the grass, and with rifle on them it's all a bit of a palaver, and certainly not the quietest of operations!
