Stephen, your "maiden voyage" was spectacular.   I cannot thank you enough for participating in the first place, but additionally for your enthusiasm, your creativity, your promotional skills, and of course the final intriguingly thoughtful production.  During my visits, I was impressed that attendees interacted with you, asking questions and lingering....a great compliment to you. Stephen, please accept my most sincere thanks for your spearheading the success of the 2013 Garden Walk Vignettes!


With great admiration, --- Peg Callard, North Dearborn Association Committee
