One of the defining characteristics of naturalists:
They haven't got enough sense to come in out of the rain.
That's Margie Hunter, author of Gardening With the Native Plants of Tennessee, educating our group about lichens, fungi, and the various worts.
The steady downpour turned out to be an enhancement to the hike at Owl's Hill Nature Sanctuary, as we well-past-21 participants gleefully scouted out plants and puddles to play with.
I'm not sure whether this suggests that the naturalist mentality requires a childlike wonder or creates it...
