Insert Slip N Slide.
I purchased the 3 lane because I thought at least two kids could go down at a time. Turns out if they time it just right - all 4 can.
At first Ben wasn't too sure. He spent a lot of time watching Madisyn, Ty and Griffin play. The far end set up to hold water. I carried him to the end and dipped his feet in the spray. Finally he came to the end and started splashing.
