That's quite common here - although slugs are able to elongate themselves, so maybe in drier conditions they like smaller. When I was a teenager I can remember having to walk down a path that was covered with big fat long slugs - it was a nightmare! I'm much more tolerant of them these days now I understand they are part of the eco system. and food chains etc.I mentioned this before, but while living in Defiance Ohio. Everytime it rained hard. These huge slugs would be on the side walks and driveways. They were like 4 or 5 inches long and thick. I was amazed!
