Gil Penalosa has traveled to more than 300 communities around the world looking for the best ideas to improve life for people of all ages. He believes the measure of a good place is whether we'd feel comfortable with an 8-year-old biking alone to the neighborhood park or someone in their 80s walking to the grocery store. 

Penalosa's philosophy:

1. lively public spaces and parks;

2. streets that are safe for everyone who uses them;

3. comfortable options for cyclists and walkers;

4. convenient, speedy public transportation;

5. public officials will to collaborate with residents
