We do have a pool, but some days, the kids just love playing with one of the sprinkler things we have or the newest addition to the water fun, a Slip N' Slide.
Check out Dan's face in this picture...priceless.

Gabe takes full advantage of the whole slide and the little pool at the end.

After repeated runs down the slide, they did go into the pool, but I guess there is a special allure to running and doing a belly flop down a wet, slippery piece of plastic.
