I was hoping maybe someone from ZipCar or Lyft would see the posting. I will take your advice and try to reach out to them directly. Believe it or not, the phone thing is a serious issue too. We had one family spending $169/mo on phone bill w/ 1200/mo in income. Maybe the ultimate solution would be somewhat of a combination of zipcar and lyft, since we don't anticipate charging for the car. (i.e. if you have one of our cars, you are somewhat obligated to give others a lift on your way). Thanks for the suggestions!
