A deal will keep the Moffett Field Commissary open for at least two more years, South Bay Democrat Rep. Sam Liccardo's office said Wednesday, preserving a key source of low-cost groceries for veterans while a long-term solution is explored. The agreement keeps the commissary operating through at least 2028, with an option to renew in 2029. Without a new lease, it had been slated to close this year a move that would have left thousands of South Bay and Peninsula veterans without nearby affordable groceries. The next closest commissaries are at Travis Air Force Base in Fairfield and in Monterey.
