Moody and Mammoth

May I?

The pavement split -took out "was"

the weeded old gravel

from bridge to -took out "strip," I think the path is already implied.

Beneath airplane calls -took out "the."

I feel like there needs to better transition from the first two lines of your second stanza with the rest. There is also an issue with tenses for me. Are we going past or present or a mix of the two (a mix being harder to accomplish.) I would suggest keep with past. Maybe something like:

we hung on open-air rafters -

and the bed of the Merrimack

broke the surface

Really enjoy the phrase "like teeth without lips/to cover them."

This last stanza, I think, could use a little re-working. I hope that this doesn't sound like I'm trying to pick apart your poem. I think it has the potential but just isn't quite there yet. Good subject as well, using a subject to portray a subject. Oh poetry, my love.

p.s. I think the title is great.
