Where can I *very* cheaply store a car with a dangerous gas leak until covid lifts and I can work towards a fix?

I have an old car with a gas leak in a gas line (along with severe corrosion issues). I’ve figured out a good plan for fixing these issues, but it involves towing it across several states with a destination that is among the worst in the country with covid at the present, and visiting that area for an extended period of time — so it would be incredibly reckless to do so at this time. As such, I need to find a way to store this car cheaply, safely, and legally until then (it might be spring when I can get vaccinated, or it could be a year).

I don’t have a garage that I can keep it in, and if I did it would probably be unwise since the gas leak is a fire hazard, and I don’t want to cause a structure fire (or a car fire, for that matter). Keeping it in the driveway is a no-go too, since the area has laws against unregistered cars being visible in public and I need to spend what little money I have on registration of a different car that I can actually drive in the meantime. Family members who have enclosed garages have refused to help since they’re worried about a structure fire, and one who doesn’t live in an area that restricts registration is worried that that fire hazard on a driveway isn’t justified (e.g. if some spark ends up on the roadway near the house, that could be a big problem).

As such, I ask how can I very cheaply (ideally for free) store this car until I can get a covid vaccine and do what I need to do to fix it? Although I lack much money, this car has incredible sentimental importance to me, so I really don’t want to sell it to a junkyard (I would be willing to pay some non-trivial money, but I don’t have it.) — although I do plan to call one to see if they’ll let me keep it there, without being for sale, in the meantime, as they are equipped for this sort of thing.
