Help finding a store

Im trying to locate my grandparents house but as a child I never remembered their address. But word is they still live in the same house. If I can locate a specific store then I believe memory will help me find it once I start driving from that store

It was either a army surplus or some type of tactical store (really small) on the side of the freeway and it had an old plane on top of the building. Does anyone know the name of the store so I can lookup the address. It would be amazing to visit them again. Thanks
