April Holidays

For the April Holidays, after all the April Fool's Jokes and Pranks are pulled, one of the important Holidays that we all should be paying attention to is Earth Day


 "Trashion Show" put on by the Truckee High School Envirolution Club

Pictured Above is the  "Trashion Show", put on by the Truckee High School Envirolution Club as part of the Earth Day Celebration at Squaw Valley in Olympic Valley, CA each year.  It was so fun!  Believe it or not, both the short skirt and the dress above, were made entirely of Bicycle Tires!
