it's because it's like the name of where i live. i live in Silverdale, which is by a river called the Lyme. near me is a park called Lymedale and quite a lot of things round here are called Lymedale something. Also, Lymedale is a mix of Silverdale and Newcastle-under-Lyme.
i was going to go with that but i tried to imagine myself using it and it just didn't seem right, so now i'm thinking i might use Harvey Hams.
