I've had many jobs and schools to commute to, and the distance has varied a lot. My most recent job was 13 miles away, so I only did the trip by bike occasionally. The other way is by subway, and that's reliable.

I'm in grad school which is 5 miles away. I do that trip almost always by bike. The other way is also by subway, also reliable.

I plan to land a new job this summer, and I want it to be at least two miles away so I can do it by bike. I'd also prefer it to be 7 miles or shorter, but I'm willing to go 11 or 12 miles.
