The thing that I really can't take about living in town is the light pollution.
I sometimes tell people I'm sensitive to light, but I really think it's the opposite - that I'm one of the lucky few who gets to live away from light pollution for most of the year, so when I'm exposed to it, I'm aware of my body's acute reaction to it, while most people just suffer sleep trouble, depression, high blood pressure, diabetes, weight gain, breast cancer, and all the other health problems linked to disruption of circadian rhythms, and they never connect it to the freakin' street lights shining in their bedroom windows.
If it weren't for street lights and security lights, I'd miss the country, but I could be fully immersed in the joys of living in town. As it is, if I had to choose one, I'd choose the country, but I do appreciate the ability to bike wherever I want to go when I'm staying in town - or walk/take transit when I'm visiting the city.
I lived for several years in a non-bikeable town. That was really the worst of both worlds. Most smaller towns in the USA are like that, I think.
