Re: the mare: maybe the trainer is just extraordinarily busy - since its show season, she may not know what time zone she's in on weekends
Just wait and if she doesn't get back to you by Wed., shoot her an email telling her of your trip to her area (of sorts) and which days you would have free to see the mare. If she's serious about selling, she will know you're a serious buyer. Sellers do hate tire kickers, and many aren't terribly forthcoming with much info other than basics, preferring you to come and see for yourself. Though if I were selling, I'd want to weed out bad fits by phone and email rather than wasting both my time and the buyer's.
