Making Myself Useful

I dream of travelling to Europe, but when I look at the price of plane tickets, hotels, rental cars, etc., I just can't justify the expense. What if I go to Poland or Italy or Portugal and volunteer to teach or help build a school? Volunteer Abroad compiles opportunities from 50 or more organizations. Most require you to pay for transportation and/or boarding, but it would be worth it to feel you're getting a behind the scenes look at a country and of course to know you're helping someone.
