Pre 9/11 was almost 20 years ago. Since then most American military installations have controlled access, meaning a DOD id card or something similar (and vehicle decals). It’s possible people might wander (especially on Army posts) onto ranges out in the sticks, but the actual garrison area will be off limits to the public (esp in the Navy and Air Force). A quick glance at Google Maps for some Canadian military installations shows them without gate guards and open to the public.
