Wanted: Taste Testers
We are searching for approximately 1 dozen elk or raindeer to help us find a bad-tasting salt for use on winter roads. No money involved...just the opportunity to be kept in a pen for several weeks and fed a variety of salts. If you like them you will not receive that kind again. Once we find a salt you dislike you will receive that one regularly.


But it worked. Now they have their elk taste testers. Way to go!
