Dana Cummings was in his thirties before he first went surfing．But，even more interesting is that Dana Cummings chose to learn the sport after losing a leg in a car accident．Now，nine years later，he helps other disabled people learn how to ride in AmpSurf．
On the coast of Maine，he is working with 27-year-old Matthew Fish，who is partly blind．Cummings grasped Fish and leads him into the ocean．The surfboard floats next to them．Fish lies on the surfboard．He tries to stand up on it．After a few attempts he stands up and riding all the way back to land．"That was exciting．"Fish says．
A car accident in 2002took Dana Cummings's leg．He says the accident changed him more than just physically．"Losing my leg makes me realize how precious life is．I do more things now than I ever did before．Next week I am going to compete in a contest in Hawaii，"Dana says．
One year later Dana Cummings formed AmpSurf．AmpSurf is a group that volunteers to holds surfing classes and events for people with all kinds of disabilities．
Recently，AmpSurf took its training programs to the East Coast．Eleven students attended the class in Maine．They had come from all over the northeastern United States．
Dana Cummings says AmpSurf can change the way a disabled person thinks．"Most people with disabilities consider himself or herself unlucky and useless，but we want them to see what they can do．Who cares you lost your leg or you're blind，whatever？Have fun．Just enjoy life．"Make the most of your life．"Dana says．
