Solving the carseat issue

So we own 3 carseats...and no car. Lugging our carseat or the booster around is a real pain. So after some research, which I actually started before the car died, and consulting Dwyers Dr. and several safety websites....It look like we are going to invest in a RideSafer Travel vest. This is a "space vest" that a regular car seat belt threads through. It is small, portable and Dwyer thinks it looks cool :)
