Web Accessibility Assessment for Everyone
The Disability Resource Center
I believe in bicyclesI believe in riding my bike to the store,riding to work, riding for fun, fitness and adventure -Road bikes, mountain bikes, single-speeds, you name it.As long as it has two wheels and a human motor, I'm on it.And I truly believe, deep down in my easily misdirected soul,that the world would be a better place if more people rode bicycles.- Don Cuerdon
