To the number of Smiths who have dropped into my life: Cindy, who has shared her energy, support, and love for so many decades; Bob, who has never hesitated to share his wife’s time and has supplied so many airline tickets to make it happen; and E.J., who has taught me so much more than I’d ever planned to learn. Thanks to you all.

Thanks, too, to Ann Hill, for her many contributions to this book and for helping to make the Michigan adventure such a memorable one; Dr. Keith Wilson, for the great escapes of shoptalk over chicken soup at Borders; Gail Lyders for her candid answers to my many questions; and Dr. Ron Wade for his time and medical expertise.
