It's gone in cycles for me. Until about 2006, I almost never traveled, outside of visiting relatives in small towns a few hours away. Then from 2006 - 2011, I traveled a lot due to studying about 500 miles from where I lived, and took several larger trips in conjunction with that. For the next year and a half, I had a job where I'd travel about once a month, so I traveled regularly then, too.
But since moving back to my hometown about two years ago, I've traveled very little. Last year, the only large city (100,000+) I visited was Cleveland, and that was more meeting up with a friend who was traveling there than actually seeing the city. I did visit a small town of 3500 or so about an hour away for the first time, and that was an interesting, outdoorsy day. But for the most part, I stayed within the city I live in and the nearby municipalities.
I hope to take at least one long-distance vacation this year, to see something different. Hopefully I'll also have at least a couple more day trip type voyages.
