Yep, know what you mean. Those squash take over. I said to my son that I would never plant a double row of squash again, because I can't get into it to harvest. His reply was, "Ya, plant a single row and leave 12 feet on each side."I can't even walk through the patch to look for fruit.
I guess he was having the same problem. I was looking at my summer squash. I planted in hills of 4 plants to a hill and they made vines that are about 4 feet long even if they are supposed to be bush type. The total area covered by a hill of these guys is about 8 x 8.
Squash are awesome.
