The city I live in is 20 miles from the city I work in. Plus I have to drive through another city to get there. Those two cities are in a different county from the one I live in. The nearest large city according to your criteria would be Minneapolis/St. Paul which is also in a whole 'nother state.
I work in both a different city and a different county from where I live, even though my home and workplace are only 15 minutes apart. Nearest major city is Denver, where I work.
I live in Brooklyn but I work in NNJ. I normally stay with my boyfriend in NJ during the week because I don’t like to commute. We head to my place on the weekends.
I don’t like living around my customers. I certainly don’t want my kids going to school with my customers and my customer’s children. I live about 25 miles away.
I live in Omaha, Nebraska, and work for a local company. I am permanently assigned to our major client. The job location is across the river in Council Bluffs, Iowa. My drive to work is about twenty five miles
Tough call. Where I work has its own police but uses the city for fire and other services - slightly but not totally independent. So I’ll say I do. And in case you are curious, I would move rather than commute daily by car - or get a different job. I did about 5 months at a job that required driving to and from (about 30 minutes each way) and almost went nuts from it. Just isn’t my bag at all.
Live in DC, work in Arlington. As a Californian, I’m constantly amazed that I can easily end up in three states (well, two states and a district) in the course of an ordinary day.
