the neighborhood junk dealers, who vandalized the murals, especially the "Barrio Sí, Yonkes No" mural created to commemorate the effort. In the mid-1990s, Caltrans decided to retrofit the San Diego-Coronado Bay Bridge to make it earthquake safe. Fearing that the murals would be damaged or destroyed, the community mobilized to stop the project to protect the murals from what they viewed as official insensitivity to the history and culture the murals represented. Eventually, a compromise was reached whereby the murals would be boarded over with plywood to protect their surfaces from damage during the retrofitting process, and would be restored to their previous condition afterward. A 2003 plan to renovate the park was stalled when Caltrans objected to the word "Aztlán", which for years had been spelled out in rocks on the park's grounds. Calling the term "militant", they claimed that using federal funding for the project would violate Title VI of the Civil Rights Act of 1964 by showing preference to Mexicans and Mexican Americans. However, Caltrans district director Pedro Orso, after consultations with civil rights experts from within the agency and from the Federal Highway Administration, decided that the word did not violate the law, and the $600,000 grant was allowed to go through.

Over 500 attended the counter-demonstration to prevent the private group from accessing the park. Ogden and his small group were eventually escorted out by dozens of police for their own safety, due to the threat from the angry crowd of park supporters. On the morning of February 3, 2018, a second "Patriot Picnic" was organized by an anonymous group, calling itself "Bordertown Patriots", with the intention of flying the U.S. flag in the center of the park. Ogden was again involved, as were a number of "patriot" figures such as Joey Gibson. Hundreds of people came to again prevent the group from entering the park. Two of the "patriots" were arrested, one for possession
