Bengt_Phorqs—<<I'll have to try the horn thing.>>
We had a chance to validate it (again) the other night. Coming out of our neighborhood at dusk (very dim light), we spotted four or five youngsters (spring fawns and yearlings) on a large lawn to our left, looking directly at us. Because they were within range to run at, or directly in front of, our car, we blasted the horn. They took off in the opposite direction at significant speed. Tentative conclusion—it works, at least with young deer. No guarantees in the case of a large, old buck (especially when he has mating on what suffices for his mind). YMMV.
Regarding why deer tend to run toward headlights: I've read several theories, and I'm too confused to buy into any of them. Is it possible that their primitive brains are programmed to run toward light when threatened by a predator because they associate light with open space that would increase their chances of escape? (Remember, deer seem to be programmed to take a linear escape route, relying on speed rather than evasiveness. This might be because they are not as agile as other species, and cannot change direction at full speed, as some African antelopes can.)
Bengt_Forqs again: <<But please...chocolate in chili? I don't think so!!!>>
Perhaps not at the Terlingua, Texico, Chile Cookoff, where attitudes toward chile tend to be fundamentalist. (I remember the controversy a few years ago between advocates of a "soupy" consistency and those of a "canned-dog-food" texture.) I assure you that in southern New Mexico, a modest amount of baking chocolate was a technique for rescuing a batch of chile that is excessively picoso. I've tried it, and I think the idea has merit. I couldn't taste the chocolate, but the potency of the chile was lessened dramatically.
Something to ponder: You question adding chocolate to chile. But in New Mexico I've eaten chocolates laced with powdered chile. Delicious! (But stick to semisweet or unsweetened choc., not milk choc.)
