Iroquois muskmelons--- There are two large ones in the top picture. One melon on the lower left and one that is difficult to see in the upper right. Here is a closeup of one of these melons.
Bush Sugar Baby watermelons. There are three in this photo. Two sitting on the pavers and the largest one on the middle right amongst the foliage. There could easily be more than three watermelons, but I didn't move the vines around to take a closer look.
