McHenry is a nice little town in northern Illinois. I've been living in McHenry for about a year and so far, it's a decent place to live. It's set back a little ways from Lake Michigan so it's a little warmer during the winter and not as windy. However, you might be hard-pressed to find a lot of fun things to do in McHenry. There's an alright amount of jobs to choose from, and a few people here commute to Chicago.
Fortunately, it's cheap to own a house or rent an apartment here. There are a bunch of parks in the city too that are good for getting some fresh air. McCollum Lake is nice, and it's probably the best area in McHenry. You'll find a bunch of stores and restaurants here too, most of them in the downtown area. Strangely, that's a part of town that the buses don't service so you will need your own car to get around.
