Los Angeles will be holding theirs at Good Samaritan Hospital on Wilshire Blvd. on May 18th from 8-9:30 AM (I may be there for that one). This will be conducted at the hospital by the on staff clergy and is a multi-faith event.
Jacksonville, Florida is getting in on the act, ride to follow.
Jackson, Michigan will be holding theirs on May, 8th.
If you are in Italy. you can drop by the shrine of Our Lady of Ghisallo, that patron saint of bicyclists. My guess is they will bless you and your bike there just about any time. You can even pick up a little medallion of the saint to put on your bike like our friend Eric did.
No matter what your belief, a few good thoughts thrown your way can not hurt. So go get your bike blessed!
