The spinning target is the best. I plan to get one more. I purchase them for about $10 each through pyramyd air. To anchor the spinning target, I drilled a hole into the 2x4 and slid the target legs through.
I changed the hoses. These blue ones are more flexible and easier for the kids to manage. I also changed out the resetting target with another spinning target. I used sand and rubber mulch for this play area. It helps to keep the water play clean. Things got pretty muddy prior to laying out the mulch.
