Sounds like the volunteers have really jumped in there. Mukilteo is a very pretty light, and has probably the best looking grounds I have seen. When Darlene was giving me a tour she explained that the local gardening club took care of the plants and all, and I can say they do a wonderful job. If i recall correctly, Darlene also noted that the club changed out the plants seasonally.
I do like the picture/poster on the festival web site. Hopefully as they get along there will be more information and pictures on it.
