Non veni pacem mittere, sed gladium.
This one definitely qualifies.
Once the cabin is finished, you should put in something like that, and of course, get the Cobra as well.
You can file this under "ambitious", but I have considered one built in an out-building where the wall is glass and can be folded back to be "outdoors". Maintaining a swimming hole of dreams in that sort of environment is not easy. I have a pool and jacuzzi at the present house and it's nice, but it's maintenance-intense. My sense was that a saltwater swimming hole of dreams would be better than one that I had to chlorinate. The devil is in the details. If I have to empty a salt water swimming hole, it's not pouring poison on the landscape.
