I love bike month! There are so many awesome activities to join throughout the whole Sacramento area. Check out the "Million Miles May" events on the following link. For those who register, there are random prize drawings. You can enter miles from biking around town, to work, to church, exercising... anytime you're on your bike. Go to the linked website and register under "Davis LDS Relief Society 2nd Ward" (apparently someone registered the ward in past years because it was already an option) :) And mark your calendars-- on May 20th from 6:30- 9:30am at the Farmers Market, the Bike to Work Breakfast is going on and for those of us that have signed up, you get a free T-shirt.
