Learning Curve Accelerator
Boomerang throwing is a learned skill, as are most other sports. Some people have natural talent and others, like myself, have to work at it. If you have thrown your 'rang and it did not come right back to you, don't worry. I doubt that a major league baseball pitcher threw a 92 mph fast ball the first day, either. Practice is the key to mastering boomeranging.
