It has taken Clair a few weeks to get used to the indoor arena. I don't know why it worried her so much -- it's really not a spooky arena at all. She keeps giving the hairy eyeball to the north door and a couple different sets of jumps along the sides. I've handwalked her around the perimeter I don't know how many times. She's much better at this point, but I still have to remember to sit back in canter lest she suddenly puts on the brakes. Silly mare.
