A Grower's Tale: Slugs?

Long ago, when I was ohh, maybe 10 or 11, or even less, I went to a week long outdoor Boy and Girl Scouts camp sponsored by my school. It was in the Santa Cruz Mountains in CA. Some older teenagers were our guides and teachers as we explored the mountains. At one point, one of the guides showed us some slugs, a brown slug and a banana slug. He swore they were edible, and licked the slime off one to prove it. He challenged us to do the same, and I, being a dork, accepted the challenge. It was just like, well, like snot, with a more earthy taste. Gag worthy? Naw, but spit worthy, for sure.
