I think it sounds like a lot of fun and the groups of kids are so small that if Lacey needs a break she can very easily get one. She's also super great with kids, it's super adorable, at my trainers house there's a little girl (she's maybe 6) that adores Lacey and she'll grab Lacey's halter and lead her around for hours and Lacey is totally good with it.
But my real question is has anyone done something like that before? How did you prepare yourself and your horse? I've worked at a camp before but that was summer camp with healthy kids and Lacey was there but the kids were not allowed to go near her.
Lacey would be being high lined and I'm not sure she's done that before, is there anything I should do to prepare her for that?
