What you do anonymously says a lot about you.
In my last year of high school, I decided to join the school's rugby team. It wasn't because I was an athlete by any definition of the word, or because I particularly knew much about the sport of rugby; it was because I wanted to visit Scotland.
You see, every year the team would "tour" a different destination, and that year they were planning a trip to the land of the Loch Ness Monster. Each member of the team was given the opportunity to offset the cost of their trip by approaching local businesses and asking them to buy an advertisement in a special publication meant to showcase the generosity of these sponsors. Many players fully funded their trips this way, as local businesses took advantage of the opportunity to support their local players (who were often family members), earn some goodwill, and generate a tax write-off. Win, win, win!
