Based on place_type, category_codes (A02010700, historic site), operating.open_hours_raw, operating.closed_days_raw, and operating.parking_available. experience_attributes.indoor_outdoor and experience_attributes.rain_safe are both null, so rain-suitability is inferred from the site type rather than an explicit field.
