Here's something else I just thought of. Find out when that law came on the books and *why.*

MN used to have a similar law - a bounty - on rattlesnakes. It's since been removed due to it being so archaic and rattlers are now, in fact, endangered. Not to mention there have been no fatal bites [to farmers, or anyone else for that matter] in the last 120 years or so.

Anyway, possibly that's the reason or something similar Maine still has that law. That should be fairly easy to research and assist in getting the law changed.
