We are here; you just don't notice us! Unless they have a pic of themselves for an avatar, or specifically mention it, you can't really tell a poster's gender.
I have been car-free for several years now, well over a decade if you count the years when my only transportation was motorcycles. I still have two motos in the carport, but neither is roadworthy and I don't have the money to fix them.
I keep thinking I really should sell them, but can't quite bring myself to do it.
As for being carefree, I suppose I was born that way and never grew out of it.
