Is it normal for a car with no overflow to dump a bit of antifreeze after a day

Thanks been a while for me with an older car , really nervous , will get an overflow tank from somewhere just so if I do se anti freeze on the ground I'll know it's trouble . This way I worry and it MIGHT be nothing .

Just part of the charm, in my opinion. As a dog lover, I would want to keep that crap off the ground, though. My '73 had a factory overflow added before I bought it.
