Chocolate! Just makes your mouth water to see that word, doesn't it? If you plan a vacation in or near Chicago, you might want to check out the Saturday courses for consumers (unless you are a professional in the food industry where courses are during the week) at the Chocolate Academy. Courses vary depending upon which chocolate chef is available or visiting. I wonder how much tasting is involved?
For the extremely adventurous, the is the Mahout Course in Chiang Mai, Thailand. If you ever wanted to get up close and personal with elephants, here's your chance. A mahout is a driver and keeper of elephants. To receive your mahout certificate, you will learn how to ride, bathe, and give commands to the elephants, basic knowledge of elephant biology and health care, and elephant art creation. There's also some Thai food cooking classes. At the end you will have earned a Mahout Certificate. I just wonder if that's license to join a circus?
A little more tame but still educational are some of the themed cruises that you can find with many cruise lines. And if you'd like a little immersion into another culture, check out some of the Work and Witness trips some church organizations offer. They have different names depending upon the denomination, but not only will you get to experience some of the culture of another country, you will donate time and talent to making others' lives better.
The world has a lot to offer. Jump in!
