It's motorbike season, and you’d better not start your engine without a blessing. A huge ceremony took place on Sunday in Poland at the shrine of Our Lady of Jasna Góra. According to the Polish Church, more than 50,000 bikers came to attend Mass and pray for a safe riding season. Fr Marek Kiedrowicz, a Franciscan and chaplain to the annual Katyń Rally motocross race, said Mass and then led the act of entrustment to the Blessed Virgin Mary. In the US too, the annual tradition of “the Blessing of the Bikes” has caught on: St Joseph’s in Bakersfield, California, was one church to host a mass blessing last weekend.
