After we unloaded Maisie and her stuff, she'd settled in a bit and I'd completed the barn's paperwork, I was able to turn her out in the indoor arena - it had just been dragged and the footing was excellent (they drag it every day). She did a little bit of exploring and some running and trotting, but settled down pretty quickly. She was even willing to follow me around, and also backed up whenever I moved towards her - I haven't taught her to do either thing explicitly and it was nice to see her so interested and engaged. She was also pretty interested in the other horses - doing some calling and looking out of the doors.
I met one of the other boarders, who seemed very nice. I can't wait to get on and ride, although that may be a few days yet - my back's slowly getting better. My daughter may ride her tomorrow.
