A few days ago I lamented the fate of a poor snail (here) which had tried to cross our driveway on a cold night and did not make it. Yesterday I spotted what I thought was that same snail about 15 feet away from his previous predicament, and lo, he had a fresh slime trail. Closer examination convinces me it's his twin brother, and not the original snail, however.
I flipped this one over temporarily to have a look inside, and he looks all fresh and ready to go on a rollicking two foot venture the next night. Perhaps my lament for the first one was premature. I guess they have to be able to take the weather around here, or they wouldn't be around here.
