Another challenge has been put forth by Mary from Chasing Mailboxes: the Errandonnee.
Basically, you have to do 12 errands which are chosen from 11 categories by bike between March 7-19, and then document your errand with a picture and something that you learned or observed during your trip.
I started this years challenge with a trip to the grocery store to pick up some tortillas for Saturday's dinner.
Category: Grocery Store
Distance: 2.34 miles
Observation 1: When there is nothing to lock your bike to at a store you tend to shop really fast.
Observation 2: Tortillas are the perfect shape to put in a frame bag.
