My opening scene drops into a sort of action sequence, but within that, uses a fair bit of subject-specific terms. To anyone familiar with the subject (horses/equestrian, with a mild western flare) these are basic, basic terms.... but I'm afraid to someone without this type of exposure might be confised, or worse, uninterested. I feel like these terms lend authenticity, give a clearer picture of the surroundings (a beginning to building my world), and I really feel like putting pause on the "action" to explain what, for instance, a halter is, and how it would be used, etc. I also feel like expaining to a less "educated" audience would insult and bore someone who knows more. I've been told both a) trust my audience. Giving credit, benifit of the doubt, etc, and b) this scene is too technical for non-horsey people. My instinct? Expect the reader to be mature: use context clues to figure out what's up. I've got a few more days before I can post for review, so looking for general opinions in the mean time.
