People park on the side the road outside the buffer zone to watch all the time. Have you been to the infinity space center on i10 at the first exit in Mississippi? Its really cool. There's real engines there you can't understand the scale of everything unless you're right there. Before the infinity center was there it was a rest area with a clone of an Apollo missionI want to go out there, one day when they do a test.
Lunar module we used to call the mosquito lol I believe there's also a command module too.
You can also do tours of stennis from there they take you on a shuttle
