The short answer is yes, I did give up my vehicle and all associated costs.
I've also never gone without food for me and the kids, if I had the boat would be gone too and it has come close but the vehicle was the money pit.
As for mandating snow tires, no I don't agree but after having gone without them for over 30 years then installing some several years back I'm now convinced they're worth it. I can't put a dollar value on my daughters safety.
