I went and had a great time. It was 200 miles for me so I had to leave about 5 am to get there. Checked all my mares before I left and nothing looked like it was close to foaling.
Lots of good presentations on feeding, tips on handling a halter horse, tips on choosing show halters, properly filling out AMHA paperwork, and others. Also a discussion with a vet on foaling out mares. I particularly loved the Q&A session. Meeting with other members and discussing topics of common interest is great!
I'm not going to attempt to pass along what I learned in writing. I have enough trouble keeping it straight myself, but it was a great day. I left a little early because I had so far to drive home, but it was well worth it.
