If you live in Michigan, you deserve a long winter cruise over tropical seas. Why face snow and ice when you can sing your song in paradise? But even paradise begins to lose its appeal when instinct tells you it's time to leave the Bahama Islands, fly north, and mate in burned-over jack pine forests. Amid the scrubby growth of these young pines, you find the specific habitat for nesting that suits you and your spouse the best. Cruising is nice, but it wouldn't be the right neighborhood to raise the kids in.
