How cool is this for innovative advocacy with lots of incredible exercise thrown in? Bike and Build organizes cross-country bike trips which benefit affordable housing groups. They have donated more than $3.3million over the last 9 years, biked over 5 million miles, taken riding breaks to contribute over 100,000 building hours towards affordable homes, and engaged over 1500 young adults. All the while raising awareness about the affordable housing crisis in America.
