Denice, basically everything you suggested is what I was planning on doing. I know one exposure wouldn't be enough to learn much of anything, but that's all I would be able to manage if I was taking a six hour round trip for just a bit of learning. If I can find someone closer to me, I will take full advantage of that.
I've been to a few trials, spoken to some people who use their dogs to move sheep about how to get started, and have a few books on training. Like I mentioned, sheep would be in the distant future, probably in three to five years and I would only get about 4-5 sheep total.
