More snails

Snail migration

Most mornings, when I go out to get the newspaper, I see a few snails crossing our sidewalk. They usually only cross from left to right, and are only there on days that our sprinkler hasn't gone off. I wonder if they cross right to left earlier in the night, and are just heading back in the morning, or what?
