Hale's Best Jumbo - Bush Type Cantaloupe?

About seven weeks ago, Keith and I met a guy through craigslist who gave us some of his gardening stuff, including some light fixtures, florescent light bulbs, dozens of small plastic pots, and lots of leftover seeds.  He told us that he had an accident several years ago, and he took up vegetable gardening as a part of his head injury rehabilitation process.  He said that vegetable gardening really helped him a lot, but now he wasn't able to continue for various reasons and he wanted to give his garden stuff away to someone who could use it.

Of all the stuff, I was most excited about my windfall of various seeds.  Unfortunately, the germination rate of some of these seeds were terrible, probably because the guy kept them in his storage unit for a couple of years before finally giving them away to us.  Only one out of the seven cantaloupe seeds germinated, and none of the seven watermelon seeds germinated. 

When I sowed these melon seeds, I knew it was probably way too late in the season to have a realistic chance of getting any melons.  But I was curious about whether the seeds would germinate at all, so I had to sow them.  When one seed germinated, I couldn't just toss the seedling away, so I'm growing it.  I will still be sad if/when the first frost kills the vine before I get any melons, but I guess that's the price I'm willing to pay to satisfy my curiosity.

The germinated cantaloupe (technically it's a muskmelon) variety is Hale's Best Jumbo, and the plant is growing more like a small upright tree and less like a typical melon vine.  The seed envelope does not have any indications, but is it possible that this variety is a bush-type?  Do bush-type cantaloupe or muskmelon varieties really exist?  Google search tells me that they do, but I could not fine any images of bush-type muskmelon plants.  Maybe mine will be the first one on the Internet!

Update:
Many helpful readers of this blog left comments on this post saying that this is most definitely not a Hale's Best Jumbo cantaloupe plant.  Not only that, it's most likely a weed.  How the seed got into the cantaloupe seed envelope, I'll never know.  It's also possible that a random weed seed just landed right in the middle of this five-gallon bucket at the same time that I sowed the cantaloupe seeds, and this plant started growing.  We're trying to figure out the identity of this plant.  It has been further discussed in another post: NOT Hale's Best Jumbo.
