Most definitely!

Heck, I've found routes that would have been annoying in a car (ed: excessive stop signs) work great on a bike. That and most major arterials tend to have a road that runs parallel to it through residential areas. These are perfect for my commute.
Colorado housing developments usually put in trails and these can help out for a mile or two. I keep discovering new ones in my area. While I tend to enjoy street riding, certain locations almost require a MUP (suburbs). Plus, I stick to the MUPs on the weekend when I have my kid in his trailer behind me. I can not convince myself to ride in the street with such precious cargo.
