The dangers are:
1. You're more exposed in the wilderness. There are less places to hide or hole up in, and you're easier to spot from a distance.
2. You're at the mercy of the elements.
3. As you said, most people think that it's safer to be out of the city, ergo you'd have more people with the same idea: run to the country.
Those three things combine to create several deadly scenarios.
1. The zombies that are out there have easier access to you. A mindless zedhead can clamber up a hill, walk around a tree or wade through a river. It can break through a wooden door or a window. By comparison, it takes an at least average human level intellect to use an elevator or open a door, and it takes human ingenuity to break through a fire door or navigate to the 30th floor of a sky scraper.
2. All those people who agreed with the notion that the country is safer will mean more zombies wandering the wilderness and more of something even more dangerous than zombies: competing survivors.
3. The large majority of the people wandering the wilderness with you will not have the skills you mentioned, which means that they're going to burn through their resources quickly and do the only thing they can do; try to take yours. Because its pitch black at night in the country, any fire you make to survive the elements I mentioned up above will be visible for miles around, attracting other survivors and zombie alike. There's less shelter (that the average uneducated bumpkin can use) meaning that whatever hole you manage to shack up in will be prime real estate that you'll have to fight others for.
Those are the major issues, and those are all issues that are not nearly as pronounced in a major city.
