I grew up in Cadillac from the time I was born until last summer (23 years). The country side is beautiful and the people are great. If you are in true downtown Cadillac there is a lot. Home Depot, Walmart, Rite Aid, and tons of restraunts. If you're a skiier Caberfea is like 10 miles west.
I'd suggest a place in Reed City. It's the same distance from Cadillac as Mesick and you are still in civilization.
If you have or plan on having kids the schools are pretty good. When I started in Kindergarden they weren't that great but when I graduated in 2002 they were a lot better.
I moved to Chicago because my work said they'd pay for me to finish my degree. As soon as my degree and assigned work term is over I'm moving back ASAP. My wife has lived in Livonia, Cadillac, and now Chicago and said she can't wait to get back to Cadillac over Chi-town or the Metro area.
Hope some of this helps
Mike
