You do have to worry. In So Cal, any cars 5 years or older need a California
smog to get a base sticker....I think it was to appease the tree-huggers
complaining about Military not being smog legal or the socialist state
of California. If you don't need a new DoD sticker likely GTG...until it expires..
Depends on which base you get it on. It is the base Co's discretion. The previous CO didn't require it. Anyways if the base requires it then, put the stocker on, get it smogged once and do what you want afterwards. Once you get the stickers it is game on.
