My husband and I have been lucky enough to have helped decorate floats a number of times (I think I've done it five times now. It's FUN -- a gigantic craft project that millions of people will see! It's also a lot of hard work, involving getting dirty and sticky from glue for long hours in a cold warehouse or tent. On taller floats, I've had to climb rafters and get into precarious positions to glue seeds or what-have-you in tight places. It's wonderful helping on the last day when all the fresh flowers are attached. All the floats really come to life with the vibrant petals and sweet scents. Unfortunately, I haven't had the time to volunteer in the last five years or so, but it would be fun to do it again someday.
Here's a few photos of this year's floats:
There are a few more float photos in my Flickr photostream.
