Cranksgiving requires participants to navigate from a starting point at Love Park to a series of designated supermarkets, you buy a food item from a shopping list and bring them to a final checkpoint at Tattooed Moms. All of the food collected is donated to a local food bank, in Philadelphia all of the food collected goes to Philabundace.
All you need is a bicycle, a lock, a backpack or messenger bag, and $15.00 to buy groceries with. You may need a map if you're not to familiar with Philadelphia or bring a a partner who is. There is no entry fee. In 2011 with 13 riders Cranksgiving Philadelphiag collected close to 200 pounds of food, from the look of their Facebook page they should easily double the amount collected.
Last year the organizers answered some questions about what inspired them to create the Cranksgiving Philadelphia and what they learned. Use this link to find out more about them and Cranksgiving.
