Took the plunge! Worked a deal out with her owner that we'd pick her up next weekend, bring her to a couple field trials, work with her at home a bit, and if we like her, we'll buy her in December. If we don't think she'll work out, we'll feed her for the winter and bring her back in March.
In the videos we've seen of her, she moves REALLY well. She's been overnight camping, ties well, high lines overnight, stands for mounting, is used to dogs, ATV's, llamas, steer, pigs, etc., goes out calmly in a group or alone, and has been shot around. Keep your fingers crossed that field trials don't send her off the deep end.
