A Surprise Muskmelon Plant I Found With Melons

We live in a rural area with a field of 10 acres around our house which has navy beans in it this year.  When we have garbage like peelings or such I sometimes throw it out in the field instead of putting it in the trash.  Well, last year we threw out muskmelon rinds with the seeds you scrape out in the field.  I recently found this plant growing with muskmelons on it.  Isn't it amazing how things grow!  We didn't have to plant the seeds and they just grew into a wonderful plant.
