Yes, Camp Pendleton had all of their stops removed, along with some off-base. You may want to see this topic, as it seems like this issue hit other USMC bases and installations, as far as we can tell.
Best advice is to try and speak with everyone that lives around the base and send word to base command asking if they have any knowledge of the removals. We are only told that a property owner removed the ones around Camp Lejeune (staff do not disclose who the property owners/managers are), and this may be the same for Camp Pendleton. Some of the players around Camp Lejeune have gotten some off-base stops/gyms back after working together to try and find out more.
