The City of Albuquerque is about to open its newest open space and residents are invited for a preview on Friday. The 23-acre site, formerly the Poole family estate, was purchased by the City and renamed the San Antonio Oxbow Bluffs (SAOB) Open Space. It has always been important wildlife habitat on the Westside, officials say. City additions including trails and an outdoor education center are now making it more accessible for residents to use, as well.
