Hey Terry,
I can also tell you what it isn't... I'm pretty sure it isn't a
tetrataenia, and I'm almost positive it isn't an
infernalis 
. Beyond that, my snake ID abilities are pretty limited
.
I can, however, tell you that the majority of the bulk on that snake appears to be in the front half of the snake. You would expect the bulk to be in rear half if it were gravid. I can't rule out the possibility that it's in the very early stages of gestation, though.
Rick
P.S. Just a word of caution... I'd strongly encourage you never to release this snake in New York, particularily if it turns out to be a
radix.
