I have yet to be able to eat escargot, and that may have cost my ex a job offer - we were taken to eat at a very fancy restaurant as part of a two-day job interview. When they brought the snails to the table, I turned a little green, tried to manage a wan smile, and said as politely as I could "no thank you". His potential boss was not pleased and urged me to try them. I tried to beg off, but he would not take a polite no for an answer, so I tried humor, and said that I've seen what snails eat. He was not amused.
Perhaps under starvation conditions I'd feel differently, but ... there's an awful lot of deer in these woods, wild turkeys, etc. so I think snails and slugs would be WAY down my list! Though I was traveling in the Pacific Northwest once, and hiking down a trail, and there was this HUGE slug right in the middle of the trail - I'll bet it was 8 inches long!!! That might actually feed someone. Slugs around here don't come quite so large!
