Do you think the pool at Haine's Point is children friendly?
Absolutely not. First, there's no kiddie pool. #2, at the shallowest point, the pool is 42 inches deep, and it moves to 48 inches deep within a few feet. So if your kid isn't into treading water at all times, he'd better be much taller than 4 feet.
As with all DC pools, no toys, balls or pseudo flotation devices are allowed. The lifeguards interpret "No Diving" off the side to also mean no jumping off the side for fun.
Lastly, the last time we were there, there were 3 or 4 adult couples who appeared to be dry humping in the water, just wandering around grinding.
