Guest, I know how you feel. I got so obsessed with saving the worms after a rainfall that I would never get where I was walking on time.
So now I have limited my rescue mission to those worms that are heading down the sidwalk. I figure those worms that are travelling crossing the sidewalk have a better chance of making it than those worms heading down the sidewalk.
As for snails, well, that is another problem.
