Happy Earth Day!
Oceanhouse Media has a novel way to celebrate if you have an iPhone (it's also iPad compatible), just download the app Lorax Garden for $2.99 and you can plant (and design) you own plants and trees in a virtual world which you can then send as postcards, keeping it green from inception to reception. You can also download the book for $3.99 and use it either as a reading and teaching tool.
If you prefer your greenery to be actual rather than virtual, the first Zipline in Los Angeles or Orange County is now open on Catalina Island. You will be traveling at speeds of up to 45 miles an hour about 300 feet up in the air over nearly .75 of a mile through five connected platform stations that hover over various areas of Catalina. Each station will teach you something about the areas you are zipping through, so this is not only an exhilarating ride, it will be educational also. It takes about 2 hours and costs $92.50, but the experience will be priceless.
