My husband works at a university in a small town. Right now, we rent about a 12-15 minute mostly highway drive away and spend about $60-70 a month on gas total. There are places he could live and be walking distance to work, but there is terrible pollution (steel mill and some sort of chemical plant) and there are high crime areas with dilapidated houses literally blocks away. The pollution is better where we're at now, but still pretty bad. To escape the pollution, he'd be looking at a 20-30 minute highway drive each way. We're really not sure what to do if he ends up staying at this job long term. We have young children and don't want to compromise their health or safety, but we'd also love to be closer to my husband's job, grocery store, etc. Also, houses near his job are more expensive with less land and we'd like to be able to grow as much of our own food as possible. What would you do?
