I just came across a poetry contest being run by the Derry Public Library. It's not specifically for metrical poetry, but the judge is Robert Crawford and the winner and runners-up get to read at the Frost Farm. There's no entry fee, and you can submit by email. Deadline March 15. Here's the
link.
Editing to add: whoops, I just noticed it says "we are looking in Derry and all over the state for the next great poem" -- so I guess it's only for NH residents? They could have been a bit more clear... Sorry about that -- I hope there are some NH Sphereans.
