Free Cantaloupes

Much to my surprise, we have had a cantaloupe vine growing along with the tomatoes. I planted cantaloupes in this same spot last year, but haven't planted any cantaloupes this year. So I guess it is growing from a dormant seed from last year. We have had four cantaloupes from this vine, so I'm calling them my free cantaloupes because I didn't have to do anything to get them.
