I see that cans are acceptable for NHC this year. The rules state that 10-14oz are preferred, but would a 16oz can be acceptable as long as it fits into the other size requirements? (9.5" high & 2.75" diameter).
I sent a note to firstname.lastname@example.org and asked the same question. If I get anything definitive from them I will post it here, but I wanted to see what the group thought before I start canning up my entries.
