Every month for the last 6 months, a group of 30-70 nudists have taken to the Ballard Pool for a night of naked swimming. It wasn’t a problem until the pool manager recently revealed that lifeguards must be at least 21 years old, not 18, and of course there aren’t many 21-or-over lifeguards. Apparently this isn’t a new rule, just recently discovered. The nudists aren’t buying it. They tell the PI that they believe this “rule change” is to limit the number of nude swims. “(The lifeguards) are legal adults,” says one of the nudists. “They have the option of not working these events if they aren’t comfortable.”
