Thanks guys, I'm leaning towards pumpkin but it's odd that it is more cylindrical than round. Haven't seen many pumpkins shaped like a cucumber/zucchini/squash also haven't seen many "round" cucumber/zucchini/squash.It's growing on a mildly steep slope if that make a difference. My experience with melons/pumpkins/squash/zucchini is limited. Have grown quite a few cucumbers in the past. I post some pics after harvest, maybe that will help.
